Immigration Law in California: A Complete Guide

Immigration is one of the highest-stakes areas of law a person can face. A single decision — whether to file a petition, how to answer a question at an interview, or whether to appear at a hearing — can determine whether a family stays together or is separated, whether a worker can keep a job, and whether a person can build a life in the United States. This guide explains, in plain English, how immigration law works for people living in California: who decides immigration status, the main paths to a green card and to citizenship, the protections available to people fleeing harm, what happens when the government tries to remove someone, and — importantly — the many ways California state law helps immigrants regardless of their federal status. It is written for everyday Californians, not lawyers.

This guide provides general information about immigration and California law and is not legal advice. Immigration is governed by federal law, the rules change frequently, and the consequences of a mistake can be severe and permanent. The right answer for your situation depends on facts that only a professional can assess. Many immigration attorneys are licensed by the State Bar of California, but immigration is a federal practice, so a lawyer admitted in any U.S. state may represent you before federal immigration agencies and courts. Before you file anything or attend any hearing, consult a qualified immigration attorney or a nonprofit accredited by the U.S. Department of Justice. Be cautious of "notarios" and unlicensed consultants, who are not authorized to give legal advice and have harmed many immigrants.

California immigration at a glance

Immigration is federal law

The single most important thing to understand is that immigration status is created and governed entirely by federal law. The main statute is the Immigration and Nationality Act (INA), supplemented by federal regulations and the decisions of federal agencies and courts. No state — including California — can grant someone a visa, a green card, or citizenship, and no state can erase a removal order. When this guide describes California laws below, those laws help immigrants live, work, drive, and study in California; they do not change a person's status under federal law.

Several federal agencies share responsibility for the system. U.S. Citizenship and Immigration Services (USCIS), part of the Department of Homeland Security, adjudicates applications and petitions — green cards, work permits, naturalization, and humanitarian benefits. The Executive Office for Immigration Review (EOIR), part of the Department of Justice, runs the immigration courts and the Board of Immigration Appeals, which decide removal (deportation) cases. Immigration and Customs Enforcement (ICE) handles interior enforcement and detention. Customs and Border Protection (CBP) manages the border and ports of entry. The Department of State (DOS), through its consulates abroad, issues visas and publishes the monthly Visa Bulletin that controls when many green-card applicants can move forward.

Green cards: becoming a lawful permanent resident

A "green card" makes a person a lawful permanent resident (LPR) — someone allowed to live and work in the United States indefinitely and, eventually, to apply for citizenship. There are several routes, but the two most common are family and employment.

Family-based green cards begin with a U.S. citizen or permanent resident filing Form I-130 for a qualifying relative. Immediate relatives of U.S. citizens — spouses, unmarried children under 21, and parents — have no annual cap and no waiting line for a visa number. Other family members fall into preference categories that are capped and often involve long waits tracked by the Visa Bulletin. We explain the categories, priority dates, and the financial sponsorship requirement in our guide to family-based green cards in California.

Employment-based green cards run from EB-1 (extraordinary ability, outstanding researchers, multinational executives) through EB-5 (investors). Many require an employer and a labor certification (PERM) proving no qualified U.S. worker is available. California's technology, agriculture, and entertainment industries generate enormous demand for these visas. See our guide to work visas and employment immigration in California.

Whichever path applies, a person already lawfully in the United States may apply for the green card through adjustment of status (Form I-485), while a person abroad goes through consular processing at a U.S. consulate.

Citizenship and naturalization

After holding a green card long enough, most permanent residents can apply to become U.S. citizens through naturalization. The application is Form N-400. The general rule is five years of permanent residence (three years for those married to and living with a U.S. citizen), plus continuous residence, physical presence, good moral character, an English and civics test, and an oath of allegiance. Citizenship brings the right to vote, a U.S. passport, protection from deportation, and the ability to sponsor more relatives. Our dedicated guide walks through every step: citizenship and naturalization in California.

Humanitarian relief: asylum, U and T visas, and VAWA

Federal law offers protection to people who have suffered or fear serious harm. These are complex, deadline-driven applications, and an attorney's help is strongly recommended.

Asylum protects people who have a well-founded fear of persecution in their home country on account of race, religion, nationality, political opinion, or membership in a particular social group. Most people must apply within one year of arriving in the United States, using Form I-589, although exceptions exist. Asylum can be sought affirmatively with USCIS or as a defense in immigration court.

The U visa is for victims of certain serious crimes who have suffered substantial harm and have helped (or are helping) law enforcement. It requires a certification of helpfulness from a qualifying agency. The T visa is for victims of human trafficking. Under California law, state and local certifying agencies have specific duties to respond to U- and T-visa certification requests.

VAWA (the Violence Against Women Act) lets certain abused spouses, children, and parents of U.S. citizens or permanent residents self-petition for status using Form I-360 — without the abuser's knowledge or cooperation. Despite its name, VAWA protects survivors of any gender. Note that immigration judges generally cannot grant U or T visas; those are filed with USCIS, even when a person is in removal proceedings.

Removal (deportation) and how people defend against it

When the government seeks to remove someone, it files a Notice to Appear (NTA) and the case goes before an immigration judge in EOIR's courts. Even in removal proceedings, many people have relief from removal available — cancellation of removal, asylum, adjustment of status, or waivers — and a person who is detained may be eligible for a bond hearing. Crucially, there is no government-paid lawyer in immigration court the way there is in criminal court; representation is generally at your own expense, though California funds programs that help. Our guide explains the process in detail: deportation and removal defense in California.

The immigration courts located in California

Because California is home to millions of immigrants, EOIR operates a large number of immigration courts in the state. These include multiple courts in the Los Angeles area (including downtown North Los Angeles Street, West Los Angeles, and Van Nuys), as well as courts in San Francisco, San Diego, Sacramento, Santa Ana, and Adelanto (a detention-based court), among others. Many hearings are now held by video. If you have a case, your Notice to Appear or your account on the EOIR system will tell you which court and judge are assigned. You can confirm your next hearing date through EOIR's automated case information line and online portal. Always keep your address updated with the court — missing a hearing can result in an order of removal entered in your absence.

California laws that help immigrants regardless of status

While California cannot grant immigration status, the state has enacted laws that make daily life more secure for immigrant Californians no matter their federal status:

• Driver's licenses (AB 60). Since 2015, eligible Californians can obtain a standard driver's license regardless of immigration status, by proving identity and California residency to the DMV. This license is for driving and identification; it does not confer immigration status.
• In-state tuition and state aid (AB 540 / California Dream Act). AB 540 allows qualifying students — including many undocumented students — to pay in-state tuition at California's public colleges and universities. The California Dream Act lets eligible students apply for state financial aid through the California Dream Act Application.
• The California Values Act (SB 54). This law limits the use of state and local law-enforcement resources for federal civil immigration enforcement, with the goal of keeping schools, hospitals, and courthouses accessible to everyone. It does not prevent federal agencies from doing their own enforcement.
• State-funded immigration legal services. Through the California Department of Social Services and programs first funded in the 2015–2016 budget, California funds many nonprofit organizations across the state to provide free immigration legal help, including naturalization assistance, affirmative applications, and removal (deportation) defense.
• U-visa and T-visa certification by California agencies. California law sets out how state and local certifying agencies must respond to requests from crime and trafficking survivors who need a certification to apply for a U or T visa, and limits the grounds for refusing.

These protections exist alongside, not instead of, the federal system. A person can hold an AB 60 license and still be in removal proceedings; a student can receive a Dream Act grant and still need a federal path to status. That is why understanding both layers — federal and California — matters.

Understanding status, visas, and green cards

The vocabulary of immigration can be confusing, so it helps to define a few core terms. A visa is, strictly speaking, a document issued by a U.S. consulate abroad that allows a person to travel to a U.S. port of entry and request admission; people often use "visa" loosely to mean their whole immigration category. Status is the legal classification a person holds once admitted — such as a student, a temporary worker, or a permanent resident. A green card is the common name for lawful permanent resident status, which allows a person to live and work in the United States indefinitely and is the usual stepping stone to citizenship. Naturalization is the process by which a permanent resident becomes a U.S. citizen. And removal (often called deportation) is the federal process for requiring a non-citizen to leave the country. Keeping these distinctions straight matters, because the rights, risks, and options attached to each are very different. A tourist who overstays, a worker on a temporary visa, a permanent resident, and a citizen all stand in very different positions under the law, even though they may live in the same California neighborhood.

It also helps to understand that immigration status is not always permanent or one-directional. People move between categories — a student may become a temporary worker, a temporary worker may become a permanent resident, and a permanent resident may become a citizen. At the same time, status can be lost: a permanent resident can, in some circumstances, be placed in removal proceedings, and a temporary visa holder who violates the terms of their stay can fall out of status. Because the system is dynamic, the best decisions are made with an eye on the whole path, not just the next form. An immigration attorney can help you see how today's choice affects tomorrow's options.

Work authorization and the right to work

Permission to work in the United States comes from federal law. Lawful permanent residents may work without restriction. Many other categories — asylum applicants, certain pending applicants, DACA recipients, and others — may apply for an Employment Authorization Document (EAD) using Form I-765. Some nonimmigrant visas, like H-1B, authorize work for a specific employer. It is important not to work without authorization, because doing so can create immigration problems. California's labor protections — minimum wage, overtime, workplace safety, and anti-retaliation rules — generally protect workers regardless of immigration status, but those protections do not substitute for federal work authorization.

Nonimmigrant (temporary) visas

Not everyone who comes to the United States seeks to live here permanently. The system includes a wide range of nonimmigrant visas for temporary purposes — tourism and business visits (B-1/B-2), academic and vocational study (F and M), exchange programs (J), temporary work in many categories (H, L, O, P, TN, E, and others), and more. Each visa has its own eligibility rules, allowed activities, and time limits, and overstaying or violating the terms of a nonimmigrant visa can create serious immigration problems down the road, including bars to returning. Some temporary visas can serve as a stepping stone toward a green card, while others do not; the difference matters a great deal when planning a long-term future. Because California's universities, employers, and cultural institutions host so many visa holders, these temporary categories are a common starting point for people who later pursue permanent residence through the employment or family paths described above.

Inadmissibility, waivers, and bars

Federal law lists "grounds of inadmissibility" — reasons a person may be denied a visa, green card, or entry — and "grounds of removability" that can put someone into removal proceedings. These include certain criminal convictions, immigration fraud or misrepresentation, prior unlawful presence, and health- or security-related grounds, among others. One of the most important — and most misunderstood — is the unlawful presence bar: a person who accrues more than 180 days or one year of unlawful presence and then departs the United States can trigger a three- or ten-year bar to returning. This is precisely why the choice between adjusting status inside the country and leaving for consular processing can be so consequential, and why no one should travel abroad during a pending case without legal advice. In many situations a waiver can forgive a ground of inadmissibility, but waivers have their own demanding requirements, often including proof of hardship to a U.S.-citizen or permanent-resident family member. Mapping out which grounds apply and whether a waiver is available is one of the most valuable things an immigration attorney can do.

Children, families, and special protections

Federal law includes protections aimed at vulnerable young people, such as Special Immigrant Juvenile Status (SIJS) for certain children who have been abused, abandoned, or neglected, which can begin with findings from a state court. Family unity is also central to the system: a green card or citizenship for one family member often opens petitions for others. Because the rules about who can petition for whom, and how long the wait is, are intricate, families planning their immigration future benefit greatly from professional advice that maps out the whole picture rather than one application at a time.

How long things take, and how to track your case

One of the hardest parts of immigration is the uncertainty around timing. Different paths run on very different clocks. Some petitions are decided in a matter of months; many family-preference and employment green cards are governed by the annual visa-number caps and can take years because of the waiting line published in the monthly Visa Bulletin; naturalization typically takes several months to a year from filing to oath; and removal cases depend on the backlog at the particular California immigration court. You can track much of this yourself: USCIS publishes processing-time estimates and lets you check the status of a pending case with a receipt number, the Department of State publishes the Visa Bulletin each month, and EOIR provides an automated information line and online portal for court cases. Keeping copies of every receipt notice, and writing down your receipt numbers and priority date, makes it far easier to follow your own case and to spot problems early.

Protecting yourself: documents and preparation

Whatever your status, a few practical habits reduce risk. Keep your important documents — passport, green card, work permit, and copies of any filings — in a safe, accessible place, and give a trusted person the information they would need to help if you were detained. Always keep your address current with USCIS and, if you have a court case, with the immigration court, because missing a notice can have severe consequences. Understand your basic rights in encounters with law enforcement, and remember that many California nonprofits offer free "know your rights" materials. Above all, get advice from a licensed immigration attorney or an accredited representative before signing anything, before traveling abroad with a case pending, and before pleading to any criminal charge if you are not a U.S. citizen. These simple precautions will not change federal law, but they can prevent the kinds of avoidable missteps that turn a manageable situation into a crisis.

Common and costly mistakes

Several avoidable errors bring serious harm in immigration cases. People miss the one-year asylum filing deadline. They fail to update their address and then receive an in-absentia removal order. They file the wrong form or rely on a "notario" instead of a licensed attorney or accredited representative. They travel abroad while an application is pending and cannot return. They plead guilty to a criminal charge without understanding the immigration consequences — even a seemingly minor conviction can trigger removal or block relief. Because immigration and criminal law intersect so dangerously, anyone who is not a U.S. citizen and faces a criminal charge should make sure their defense lawyer consults an immigration attorney before any plea.

Avoiding immigration fraud and "notario" scams

A vulnerable audience attracts predators, and immigration is no exception. Across California, unlicensed "notarios," "immigration consultants," and outright fraudsters take money from immigrants in exchange for promises they cannot keep. In many Latin American countries the word "notario" refers to a high-level legal professional, but in the United States a notary public is not a lawyer and cannot give legal advice or represent you. Only a licensed attorney or a representative accredited by the U.S. Department of Justice may give immigration legal advice and represent you before USCIS and the immigration courts. Warning signs of a scam include guarantees of a particular outcome, pressure to sign documents you do not understand, requests to file for benefits you may not qualify for, and refusal to provide a written contract or a copy of your own paperwork. If you have been victimized, California law provides avenues to report unauthorized practice. The safest course is to verify that anyone helping you is a licensed attorney or accredited representative before paying any money or signing anything.

Putting the pieces together

Immigration can feel like a maze because it really is a layered system: a federal framework that decides status, a set of federal agencies and courts that administer it, and a separate layer of California laws and programs that make daily life more secure for immigrant Californians without changing federal status. The four detailed guides linked throughout this page — on family-based green cards, work visas and employment immigration, citizenship and naturalization, and deportation and removal defense — go deeper into each path. For most people, the wisest first step is a consultation with a licensed immigration attorney or an accredited nonprofit who can look at the whole picture, identify the strongest path, and warn against the missteps that cause the most harm. With accurate information and good representation, what looks overwhelming at first often becomes a clear, manageable plan.

Fees, forms, and where to verify them

Immigration involves federal forms and filing fees that change over time. As examples, recent USCIS fees include roughly $675 for Form I-130 and about $1,440 for Form I-485 (adjustment of status); naturalization on Form N-400 is about $760 by paper or $710 online, with reduced-fee and fee-waiver options for those who qualify. Always confirm the current fee and the correct edition of any form directly on the USCIS website before filing, because amounts and rules are updated periodically. Filing an outdated form or the wrong fee can cause a rejection and lost time.

Frequently asked questions

Can California give me a green card or stop my deportation?

No. Only the federal government can grant immigration status or decide a removal case. California laws can help you drive, study, and access services, and California funds legal-aid programs that may represent you, but the state cannot grant status or override a federal removal order.

Do I need a lawyer licensed in California to handle my immigration case?

Not necessarily. Immigration is federal, so an attorney admitted in any U.S. state, or a representative accredited by the Department of Justice, may represent you before USCIS and the immigration courts. Many California immigrants choose local attorneys licensed by the State Bar of California for convenience, but the key is that the person is a licensed attorney or accredited representative — not an unlicensed "notario."

If I have an AB 60 driver's license, can it be used against me?

An AB 60 license is designed for driving and identification regardless of immigration status, and California law restricts using it as a basis to detain or arrest someone solely because of immigration status. As with any legal question that affects you personally, it is wise to confirm current rules with an attorney.

I'm undocumented. Can my U.S. citizen child sponsor me?

A U.S. citizen child can file a family petition for a parent only after the child turns 21. Even then, whether you can actually obtain a green card depends on many factors, including how you entered the country and your immigration history. This is a common situation with complicated rules — talk to an immigration attorney about your specific facts.

Is there free immigration legal help in California?

Yes. California funds nonprofit organizations statewide to provide free immigration legal services — including naturalization help, affirmative applications, and removal defense — through the Department of Social Services and county programs. Availability varies by location and case type, so contact local nonprofits early.

I'm afraid to go to my immigration court hearing. What happens if I don't?

Skipping a scheduled hearing is one of the most damaging things you can do: the judge can order you removed in your absence. If you are afraid or confused, get a lawyer's help, but appear. Always keep your address current with the court so you receive notices.

Will using public services hurt my immigration case?

The "public charge" rules are complex and have changed over time, and many benefits — including emergency care and benefits used by U.S.-citizen family members — are not counted. Because the rules are nuanced and consequential, ask an immigration attorney before declining services you or your children may need.

How long do immigration cases take?

It varies enormously. Some petitions are decided in months; family-preference green cards can take years because of visa-number limits; court cases depend on the local docket. The Visa Bulletin and USCIS processing-time pages give estimates, but a lawyer can help you understand the timeline for your specific path.

What is the difference between USCIS and the immigration court?

They handle different things. USCIS, part of the Department of Homeland Security, decides applications and petitions — green cards, work permits, naturalization, and humanitarian benefits. The immigration court, run by EOIR within the Department of Justice, decides removal (deportation) cases before an immigration judge. Some matters move between them: for example, a person in removal proceedings may still file certain applications with USCIS. Knowing which agency has your case tells you where to send filings and how to check status.

Is DACA still available, and does it give me a green card?

Deferred Action for Childhood Arrivals (DACA) is a federal program that has been the subject of ongoing litigation and policy changes, so its availability and rules can shift. Importantly, DACA is not a green card and does not by itself create a path to permanent residence or citizenship — it is a form of temporary protection from removal with work authorization for those who qualify. Because the program's status changes, check the current rules with a licensed immigration attorney or accredited nonprofit before relying on it.

Can I travel outside the United States while my case is pending?

Often this is risky. Depending on your status and the type of case, leaving the country can cause your application to be considered abandoned, can trigger the three- or ten-year unlawful-presence bars, or can prevent you from returning at all. Some pending applicants can obtain "advance parole" to travel, but not everyone qualifies. Never travel abroad with an immigration matter pending without first getting advice from an immigration attorney.
