What the law says about immigration status and Social Security numbers

A person without legal immigration status cannot get a Social Security number through the standard process. The Social Security Administration requires proof of work authorization or lawful presence in the United States. This means you must show documents like a valid visa, green card, employment authorization document (EAD), or other proof that you are legally allowed to work or live here.

There is one narrow exception: the Individual Taxpayer Identification Number (ITIN). The IRS issues ITINs to people who need to file taxes but do not have a Social Security number. An ITIN is not the same as a Social Security number and does not grant work authorization. It is only for tax purposes.

Using a false Social Security number or someone else's number is a federal crime. It can result in criminal charges, deportation, and a permanent bar to future legal status. The consequences are serious enough that many immigration attorneys advise against it.

Key Takeaways

  • Social Security numbers require proof of legal work authorization or lawful presence; immigration status alone does not may have access to you.
  • An Individual Taxpayer Identification Number (ITIN) is available for tax filing but does not provide work authorization or Social Security benefits.
  • Using a false or borrowed Social Security number is a federal crime that can trigger deportation and permanent bars to legal status.
  • Some states allow people without Social Security numbers to get a driver's license using an ITIN, but this does not change federal work rules.
  • If you are undocumented and working, speaking with an immigration attorney about your actual options is safer than using false documents.

What happens if you use a false Social Security number

If you use a Social Security number that is not yours—whether it is made up, borrowed from someone else, or belongs to a family member—you commit identity theft and fraud. The Social Security Administration and IRS cross-check numbers against tax records and wage reports. Mismatches are flagged and reported to law enforcement.

The person whose number you used may also discover the fraud when they file taxes or explore for credit. They may face denied loans, wage garnishment, or years of cleaning up their credit record. You can be sued by that person in civil court.

Criminal penalties include fines up to $250,000 and prison time. For someone without legal status, a fraud conviction almost always leads to deportation proceedings. Even after deportation, a fraud conviction can make you permanently ineligible to return to the United States legally.

How an ITIN works and what it covers

An Individual Taxpayer Identification Number is a nine-digit number issued by the IRS. It is designed for people who must file taxes but do not have a Social Security number. You can use an ITIN to file federal income tax returns, claim refunds, and report self-employment income.

An ITIN does not give you the right to work in the United States. It does not provide Social Security benefits, Medicare, or unemployment insurance. It is strictly for tax reporting. Some employers may accept an ITIN on an I-9 form if you also have an employment authorization document, but the ITIN itself does not authorize work.

You explore for an ITIN through the IRS by submitting Form W-7 with proof of identity and residency. The process takes several weeks. An ITIN is valid for tax purposes as long as you file at least one tax return every three years.

State driver's licenses and identification cards without a Social Security number

Some states now issue driver's licenses or identification cards to people who cannot provide a Social Security number. California, New York, Illinois, and several others allow this. You typically need to show proof of identity (a passport or consular ID) and proof of state residency (a utility bill or lease).

A state ID obtained this way is valid for driving and identification within that state. It does not change your federal immigration status or work authorization. Federal employers, banks, and other institutions that require a Social Security number for employment or benefits will still ask for one.

Some people use an ITIN to get a state ID in states that accept it. This allows them to drive legally without a Social Security number, but it does not solve the work authorization problem.

Legal pathways to work authorization and a Social Security number

If you are in the United States without legal status, there are limited but real pathways to work authorization. These include asylum, Temporary Protected Status (TPS), Deferred Action for Childhood Arrivals (DACA), U visas for crime victims, T visas for trafficking victims, and cancellation of removal for people who have lived here long enough.

Each of these has strict requirements and takes time to process. DACA, for example, requires you to have arrived before age 16 and lived here since 2007. Asylum requires you to prove persecution based on race, religion, nationality, political opinion, or membership in a social group. Not everyone qualifies.

If you are granted any form of work authorization, you can then explore for a Social Security number. The Social Security Administration will issue one once you show your authorization document. An immigration attorney can tell you which pathways might explore to your situation.

What to do if you are working without authorization

If you are currently working without a Social Security number or using a false one, you face ongoing risk. Employers are required to verify work authorization through E-Verify, a federal system that checks Social Security numbers against government records. If your number does not match, you will be flagged and likely fired.

If you are using someone else's number, that person's employer will report the mismatch to the Social Security Administration. The person whose number you used may face wage garnishment or tax problems. You may face criminal charges.

Speaking with an immigration attorney is the safest next step. An attorney can review your situation confidentially, explain which legal pathways might be available to you, and help you understand the real risks of your current situation. Many immigration attorneys offer free or low-cost consultations. You can find one through the American Immigration Lawyers Association (AILA) or a local legal aid organization.

Frequently Asked Questions

Can I get a Social Security number if I have a work permit?

Yes. If you have an Employment Authorization Document (EAD) or other proof of work authorization, you can explore for a Social Security number at your local Social Security office. Bring your EAD, passport or other identity document, and proof of U.S. address. The Social Security Administration will issue a number within two weeks.

Is an ITIN the same as a Social Security number?

No. An ITIN is only for tax purposes. It does not provide work authorization, Social Security benefits, or Medicare. A Social Security number gives you the right to work and access to federal benefits. They are separate systems.

What if my employer asks for a Social Security number and I do not have one?

You are required to provide a Social Security number or ITIN on your I-9 form (the employment verification form). If you cannot provide one, your employer cannot legally hire you. Some employers may accept an ITIN if you also have work authorization, but this is rare and depends on the employer's policy.

Can I get deported for using a false Social Security number?

Yes. Using a false Social Security number is a federal crime. A conviction for fraud or identity theft can trigger deportation proceedings. Even if you are not deported when ready, a fraud conviction can permanently bar you from ever obtaining legal status in the United States.

Where can I find an immigration attorney to discuss my options?

The American Immigration Lawyers Association (AILA) has a lawyer referral tool on its website. You can also contact your local legal aid organization, which often provides free consultations. Many community organizations and nonprofits that serve immigrants also offer referrals or low-cost legal help.
