Do I need to register for Selective Service if I am undocumented?

This page is about the duty to register. It is general information, not legal advice. If you are applying for citizenship and need proof you registered, go to Selective Service and citizenship: how to check if you registered.

Do I really have to register if I have no papers?

Yes. Selective Service says immigrant men must register, and its list of who must register includes undocumented immigrants (Selective Service, Who Needs to Register). Its FAQ says all undocumented males 18 through 25 must register, except men admitted on nonimmigrant visas (Selective Service FAQ).

This covers you whether you are undocumented, have DACA, have TPS, are waiting on asylum, or have a green card. Selective Service has told DACA recipients to register too (Selective Service toolkit for immigration attorneys).

Who does not have to register:

• Men who are in the U.S. on a valid nonimmigrant visa (such as a student or work visa) and stay on a valid visa until they turn 26 (Who Needs to Register).
• People assigned female at birth. Selective Service says people assigned male at birth must register even if they later changed their gender to female. People assigned female at birth who changed their gender to male do not have to register.
• Men serving full time on active military duty the whole time from 18 to 26.

Does registering mean I join the military or go to war?

No. Registering puts your name on a list the government would use only if Congress and the President brought back a draft in a national emergency (Selective Service FAQ). Immigrants Rising notes there has been no draft since the 1970s. Registering does not sign you up for the military and does not make you a soldier.

Why does it matter for someone without papers?

Because your future can change. Many people who are undocumented at 18 later get a green card through family, a U visa, a court case or another path. Then they apply for citizenship. The citizenship form asks whether you registered.

USCIS can deny citizenship to a man who knowingly and willfully failed to register when he had to, if he applies within a set time after turning 26 (USCIS Policy Manual, Volume 12, Part D, Chapter 7). Registering now, while you can, removes that problem.

Failing to register on purpose is also a federal crime. The law allows a fine of up to $250,000, up to 5 years in prison, or both (Selective Service, Benefits and Penalties). Selective Service also lists most federal jobs and federal job training under the Workforce Innovation and Opportunity Act (WIOA) as tied to registration, and says many states tie their own student aid and jobs to it.

Federal student aid no longer requires it. The U.S. Department of Education removed the Selective Service requirement for federal student aid in 2021 (Federal Register notice, June 17, 2021). For California aid for undocumented students, see Paying for college in California, whatever your status.

How do I register without a Social Security number?

You can. Selective Service says you do not need a Social Security number to register. If you have one, you must give it (Selective Service FAQ).

The online form asks for a Social Security number. Without one, use paper:

1. Go to any U.S. Post Office and ask for the Selective Service registration form, SSS Form 1. The FAQ also offers a printable form.
2. Fill it out in ink. Use your full legal name, date of birth and a mailing address where you can safely get mail for months.
3. Leave the Social Security number blank if you do not have one. Never write an ITIN or a number that is not yours.
4. Put postage on it and mail it.
5. Ask the post office clerk for proof of mailing, and keep a copy of what you sent. A nonprofit guide from Immigrants Rising gives the same tip.

If you get stuck, call Selective Service at 888-655-1825, Monday to Friday, 9 a.m. to 5 p.m. Eastern (Selective Service, Contact Us). Its Register page also tells people without a Social Security number to contact it (Selective Service, Register).

What happens after I mail it?

Selective Service mails you a registration acknowledgment card. It can take up to 90 days to process a mailed form. If no card arrives after 90 days, call 1-847-688-6888 (Selective Service FAQ).

When the card comes, keep it forever with your birth certificate and other important papers. Take a photo of it too. You may need it years from now for a green card or citizenship case. If you move, use Selective Service's Update Your Information page.

What information does Selective Service get, and who can see it?

The form asks for your name, home address, date of birth and Social Security number if you have one (Selective Service, Register). It does not ask about immigration status.

We read Selective Service's Privacy Act statement on October 21, 2026. It lists who may receive registration records. That list includes:

• the Department of Justice, to look into suspected violations of the draft law;
• the State Department and USCIS, to decide eligibility for entry to the U.S. and for citizenship;
• the Department of Defense, including for military recruiting;
• the Department of Education, for student aid;
• state and local governments, to help enforce state and local law;
• the public, for your name, registration number, date of birth and classification.

The statement does not name ICE or the Department of Homeland Security as a whole. We are being straight with you: it does list law enforcement uses, and we cannot promise how any agency will act. Your name and address are what the form shares. If your situation is complicated (for example, you have a removal order or a criminal case), talk to a lawyer or DOJ accredited representative before you mail the form. Free help is listed below.

I am 17. What should I do?

Wait until you are close to 18. Immigrants Rising says Selective Service cannot accept registrations from people under 18 and suggests mailing the card no earlier than 30 days before your 18th birthday. Then you have 30 days after your birthday to get it done (Who Needs to Register).

Parents and school counselors: put a reminder on the calendar for the month of the 18th birthday.

I came to the U.S. after I turned 18. Do I still register?

Yes, if you are under 26. Immigrants who arrive between 18 and 25 must register within 30 days of arriving (Who Needs to Register). If you missed that 30 days, register now. Selective Service accepts late registrations until a man turns 26 (Selective Service FAQ).

I am 26 or older and never registered. Now what?

You can no longer register. Selective Service says that once you turn 26, it is too late (Selective Service FAQ).

That does not close every door. What matters later is whether your failure was "knowing and willful" and how old you are when you apply for citizenship. USCIS looks at men ages 26 through 30 case by case and gives them a chance to explain. From 31 (or 29 on the marriage path), it no longer counts against you (USCIS Policy Manual, Volume 12, Part D, Chapter 7). A man who did not know he had to register can explain that.

If you are 26 or older and never registered, write down now why you did not: where you lived, whether anyone told you, whether you knew. Then talk to a lawyer before any future green card or citizenship filing. Our citizenship and Selective Service guide explains the age table and the status information letter.

Will I be registered automatically?

A federal law signed on December 18, 2025 rewrites the registration law so that men in the registration age range "shall be automatically registered" by Selective Service. That change is scheduled to take effect one year after the law was signed, around December 18, 2026 (50 U.S.C. 3802 and notes, Cornell LII; Pub. L. 119-60, section 535). As of October 21, 2026, the Selective Service FAQ does not explain how automatic registration will work.

Until Selective Service says otherwise, the rule today is the same: register yourself. If you were automatically registered later, you lose nothing by having registered first.

We found no California law that registers men through the DMV. A 2015 bill to do that (AB 82) was vetoed (AB 82 history, LegiScan). So do not count on an AB 60 license to register you. See Driver's license without papers.

Common mistakes to avoid

• Waiting until 26. After that, it is too late.
• Using someone else's Social Security number or a made up one. Leave it blank if you have none.
• Throwing away the card. Keep it with your important papers for life.
• Thinking DACA or TPS excuses you. It does not.
• Paying someone to register you. You can do it yourself, online or with the paper form at the post office. Anyone charging to register you is a red flag. See Warning signs of an immigration scam.

Is there a checklist I can print?

Questions people ask

Does registering give me any status or protect me from deportation? No. It is not an immigration benefit.

Can I join the military after registering? Registering does not make you eligible. Immigrants Rising notes that generally only citizens and green card holders can enlist.

What if my name has a hyphen or accent? Selective Service's system replaces punctuation in names with a space (Selective Service FAQ). Use your name as it appears on your birth certificate or passport.

I have dual nationality. Does that change anything? No. Dual nationals register within 30 days of turning 18 (Who Needs to Register).
