The Work That Doesn’t Show Up on Paper
Marco Reyes spent almost two decades working in California without authorization, paying into systems he couldn’t draw from, building a life that existed in one world while his paperwork existed in another. His situation wasn’t unusual. Millions of people in California go to work every day knowing their employment isn’t authorized under federal law, and most of them understand the risks only in the vague, anxious way that comes from never having seen them written down plainly.
This page lays out what unauthorized work actually means in legal terms, what the immigration consequences can look like, what California law still protects regardless of status, and why filing taxes even without authorization can matter more than most people realize. None of this is legal advice for your specific situation, and if you’re currently working without authorization, the single most important thing on this page is the recommendation to talk to an immigration attorney before making any decisions that could affect a future case.
What Unauthorized Work Actually Means
Under federal immigration law, working without authorization means performing labor or services for an employer, or operating as self-employed, without a valid Employment Authorization Document (EAD), a work visa, or another status that grants the right to work in the United States. The definition is broader than people expect. It doesn’t require a formal employer-employee relationship, and it doesn’t require a paycheck with a name on it.
Using someone else’s Social Security number to get hired counts. Using a fake Social Security number counts. Working for cash with no paperwork at all counts. Continuing to work after an EAD has expired counts, even if a renewal application is pending and even if the gap is only a few weeks. For many renewal applicants, a pending renewal no longer provides the automatic extension it once did for applications filed on or after October 30, 2025, which means the safety net that existed in many cases before then may no longer apply, per the USCIS announcement (as of June 2026). Working on a visa that doesn’t include work authorization, like a tourist visa, counts from day one. The legal definition isn’t interested in the reason or the intent. It looks at whether the person had the legal right to work at the time the work happened.
This matters because immigration law doesn’t distinguish between a person who knowingly used a fraudulent document and a person who simply didn’t realize their authorization had lapsed. The consequences attach to the fact of unauthorized employment, not to the moral character of the worker.
Immigration Consequences
Unauthorized work can affect an immigration case in several ways, and the effects depend heavily on individual circumstances, which is why this section describes the landscape rather than predicting what would happen in any particular situation.
Unauthorized work can also create admissibility issues for anyone who leaves the United States and tries to return. If a person has accrued unlawful presence, meaning time spent in the country without valid immigration status, leaving the country can trigger three-year or ten-year bars to reentry depending on how long the unlawful presence lasted. Working without authorization doesn’t by itself create unlawful presence, but the two often overlap because the circumstances that lead to one frequently lead to the other.
Using false documents to obtain employment can carry its own separate consequences, including potential findings of misrepresentation that create a permanent bar to admissibility unless waived. In some cases, the most serious issue isn’t the unauthorized work itself but whether the person made a false claim to U.S. citizenship on employment paperwork, which carries even harsher consequences and, under the USCIS Policy Manual (as of June 2026), generally has no waiver available for this ground. A person who used a false Social Security number a decade ago may face a different set of risks than someone who worked for cash with no documents at all, and the difference can shape what options are available going forward.
None of this means that a person who has worked without authorization has no path forward. Many people with this history go on to obtain legal status through family petitions, waivers, or other channels. But the history is a factor, and understanding that it’s a factor is better than pretending it isn’t.
California Protections That Still Apply
Here is where California diverges from what many people expect, and from how things work in most other states. Under California law, a worker is a worker. Immigration status does not determine whether labor protections apply. This isn’t a feel-good abstraction. It’s enforceable state law, backed by specific statutes and by agencies with the authority to investigate and penalize employers who violate it.
If an employer doesn’t pay you for hours worked, that’s wage theft, and it’s illegal regardless of your immigration status. If you’re injured on the job, you’re entitled to workers’ compensation benefits. California’s Division of Occupational Safety and Health (Cal/OSHA) protections apply to every worker in the state. The minimum wage applies to every worker. Overtime rules apply to every worker. None of these protections ask about your Social Security number.
Two California laws are particularly important here. AB 263 and SB 666, both passed in 2013, make it illegal for an employer to retaliate against a worker by threatening to report them to immigration authorities (as of June 2026). An employer who threatens to call ICE because a worker filed a wage complaint or reported unsafe conditions is breaking California law. The state Labor Commissioner’s Office can investigate these complaints, and an employer found to have retaliated can face serious penalties, including a court order to suspend their business license.
This protection exists because California recognized a basic reality: if employers can silence workers by threatening deportation, then every labor law on the books becomes unenforceable for a significant portion of the workforce. The protection isn’t about immigration status. It’s about making sure labor law works for everyone.
That said, being honest about limits matters too. These protections apply under California law, enforced by California agencies. They don’t prevent federal immigration enforcement from operating independently. If ICE has its own reasons to be at a worksite, California labor protections don’t override federal authority. What they do is ensure that an employer can’t weaponize immigration status against a worker to avoid paying wages or maintaining safe conditions. That distinction is important. For more on what happens if enforcement shows up at a workplace, see the page on your rights during a workplace encounter.
Tax Implications
This is the part that surprises people, and it’s worth understanding clearly: you can file federal and state taxes without work authorization, and in many situations, doing so can help a future immigration case. But the privacy landscape around tax filing has changed significantly since 2025, and anyone making filing decisions needs current information.
The mechanism is the Individual Taxpayer Identification Number, or ITIN. The IRS issues ITINs to people who need to file taxes but aren’t eligible for a Social Security number. For decades, the IRS maintained strict separation from immigration enforcement, and filing taxes with an ITIN carried no realistic risk of the information reaching immigration authorities. That changed in 2025. The long-standing separation between tax filing and immigration enforcement has been tested: the federal government moved to share some taxpayer information with immigration authorities, and that move has been challenged in court, with the situation shifting as the cases proceed. Because where this stands keeps changing, anyone weighing whether to file should check the current status through a trusted source like the Congressional Research Service litigation tracker (as of June 2026), and talk with an immigration attorney or legal aid organization before deciding.
This doesn’t mean you shouldn’t file taxes. Immigration attorneys continue to advise filing, and the reasons remain strong. But it does mean the decision should be made with eyes open and, ideally, after talking to an immigration attorney or accredited representative who can assess your individual situation. The privacy assurances that were accurate two years ago no longer reflect how the system is actually operating.
Why bother filing taxes if you’re not required to? Several reasons, and they’re practical rather than moral. First, if you ever apply for legal status, USCIS may ask for tax records. Having a clean filing history demonstrates good moral character, which is a formal legal requirement for many immigration benefits including naturalization. Showing that you’ve been paying taxes during years of unauthorized work doesn’t erase the unauthorized work, but it’s a positive factor in a discretionary analysis. Immigration attorneys routinely advise clients to file, and the reason is simple: it’s easier to show USCIS four years of filed returns than to explain four years of silence.
Second, filing taxes can make you eligible for certain tax credits. The rules for the federal Child Tax Credit have tightened in recent years, and the Social Security number requirements that now apply can leave ITIN-only filers unable to claim it, so check your current eligibility before you count on it. California’s Young Child Tax Credit, which covers a qualifying child under six and is tied to the state Earned Income Tax Credit, may still be within reach for many ITIN households; confirm the current eligibility rules and amount with the Franchise Tax Board (as of June 2026). Check the tax filing page for more on which credits you may be able to claim.
Third, tax records serve as a form of documentation. They establish that you were present in the United States, that you were working, and that you were participating in the system. For any future application that requires proving continuous physical presence or establishing a timeline, tax records are among the strongest pieces of evidence available.
Filing taxes doesn’t legalize unauthorized work, and it doesn’t create any kind of immunity. But it creates a record that an immigration attorney can use to build the strongest possible case when the time comes.
If You’re Currently Working Without Authorization
If this describes your situation right now, the most useful thing this page can do is be direct without being judgmental. You already know the risks exist. What you may not know is what to do about them.
Start by talking to an immigration attorney or accredited representative. Not because something has gone wrong, but because understanding your specific situation is the only way to know what options you actually have. Free and low-cost legal help is available throughout California, and a consultation doesn’t commit you to anything. It gives you information. Many people discover they have more options than they thought, and some discover that what they’ve been doing isn’t as risky as they feared. Either way, knowing is better than guessing.
While you’re figuring things out, document everything about your employment. Keep records of hours worked, wages paid, and any communications with your employer. If you’re paid in cash, write it down, dates and amounts. If your employer ever threatens you, says anything about your immigration status, or retaliates against you for asserting your rights, document that too. These records matter, both for labor claims if you ever need to file one, and for immigration purposes if you need to establish a timeline later.
Know your labor rights now, before you need them. Don’t wait until there’s a problem. California protects your right to be paid fairly, to work in safe conditions, and to report violations without your employer retaliating by threatening your immigration status. These protections exist whether or not you have work authorization, and knowing about them before a crisis hits puts you in a stronger position.

Next Steps
If you’re working without authorization or have done so in the past, the first and most important step is a consultation with a qualified immigration attorney or accredited representative who can assess your individual situation. Free and low-cost legal services are available across California through the organizations listed on our Find Help page. A single consultation can clarify whether your work history creates a problem for a future case and, if so, what can be done about it.
If you haven’t been filing taxes, consider starting, but talk to an immigration attorney first about the current landscape around IRS data and immigration enforcement before making that decision. Review the ITIN page to understand how to get a taxpayer identification number, and the tax filing page for guidance on filing without a Social Security number. If you’ve missed years, a tax professional experienced with ITIN filers can help you file back returns.
If you’re currently employed and concerned about your rights at work, read the full breakdown of labor protections that apply regardless of immigration status. If your employer has threatened to report you to immigration authorities, that threat is itself a violation of California law, and you should document it and seek help immediately.
