Social Security Numbers and Cards for Noncitizens

If you are a noncitizen with permission to work in the United States, you can get a Social Security number, and you should — employers report wages against it, banks and landlords ask for it, and tax filing is simpler with it. The Social Security Administration also issues numbers to people without work authorization, but only in narrow circumstances, essentially where another federal or state law requires a number for something other than employment. There is no general-purpose Social Security number available on request, and no version of it that grants permission to work.

The agency's own instructions live at ssa.gov/ssnumber, and the process differs depending on how and when you arrived.

Three cards, one number

The number is permanent. If your status changes — a work permit holder becomes a permanent resident, a permanent resident naturalizes — the number stays the same and you request a replacement card to remove the legend. People sometimes assume they need a new number after naturalizing; they do not, and asking for one is a red flag rather than a routine request.

Worth knowing: The card itself is not an identity document in the way a passport or driver's license is. It carries no photograph and no expiration date. Employers accept it as a List C document under Form I-9, meaning it shows work authorization only and must be paired with an identity document.

Applying for the number

There are two broad routes, and taking the first one where it is available saves a trip.

Tip: If you applied for a work permit on Form I-765, look at whether you completed the Social Security number request section on that form. Doing so is the simplest route and avoids a separate application entirely.

Non-work numbers

A non-work number is issued when a federal or state law requires a Social Security number to get a particular benefit or service, and the applicant cannot get a number on the usual work-authorized basis. The applicant has to show the legal requirement — typically a letter from the agency administering the benefit, citing the law that requires the number.

What a non-work number is not: a workaround for a lack of work authorization, a general identification number, or a route to a bank account or a driver's license. Where the need is tax filing rather than a benefit, the correct instrument is usually an ITIN from the IRS instead. Our guide on filing taxes with an ITIN instead of a Social Security number covers that route, including the fact that an ITIN confers no work authorization and no status.

Careful: Using someone else's Social Security number, or a number that was never issued to you, is a serious offense with consequences that reach well beyond the immigration system. It also creates a record that follows you into every future application, including naturalization.

If that has already happened, the worst response is to answer a form question about it by guessing. A firm offering immigration services for individuals, or an accredited nonprofit, can assess the exposure and the disclosure obligations before you sign anything under penalty of perjury, which is the point at which a bad answer becomes a second problem on top of the first.

Students, exchange visitors, and derivative spouses

Nonimmigrant students and exchange visitors generally need to show that they have actually been authorized to work — a job offer for on-campus employment, or the relevant authorization document — before a number is issued. Being enrolled is not itself work authorization. Spouses in categories that permit employment usually need their own authorization document first.

Because the requirements differ by category and the Department of State and USCIS control the underlying permission, check both the SSA instructions and the Department of State visa pages for your category. Schools' international student offices generally know the local field office practice, which varies more than the national instructions suggest.

State agencies build their own rules on top of this. Whether a Social Security number is required for a driver's license, and what substitutes for it, differs by state — see driver's licenses and state IDs for noncitizens. Some cities issue municipal identification that asks for none of this; see municipal ID cards and what they can be used for.

Common questions

Can I start work before my Social Security card arrives?

Generally yes. Work authorization comes from your immigration permission, not from the card, and the employment verification form does not require a Social Security number in every situation. Employers enrolled in E-Verify do need the number to create a case, so there may be a practical wait. Tell the employer that the application is pending rather than letting them assume you lack authorization.

I became a permanent resident. Do I need to tell Social Security?

You should request a replacement card so the restrictive legend is removed, using the same number you already have. It matters for future employment verification, because a card reading "valid for work only with DHS authorization" invites reverification questions you no longer need. Bring your permanent resident card as proof of the change, and expect the replacement to arrive by mail.

My name changed. Does the card have to match my other documents?

Yes, and mismatches cause real problems with wage reporting and with employment verification. Update the record with SSA when a name changes through marriage, divorce, or a court order, and keep the spelling consistent with your immigration documents. Where a transliteration difference exists between a foreign document and a U.S. one, resolve it early rather than at a job's first payroll run.

Does having a number help my immigration case?

Not directly. It is not a status, and it is not evidence of eligibility for anything. What it does is create a wage record, which can matter later for tax compliance, for showing employment history, and for the work quarters that end certain sponsor support obligations. It is administrative infrastructure rather than an immigration benefit, and it should not be described as one.
