Military Selective Service Act: Registration and Penalties

The Military Selective Service Act requires nearly every man living in the United States, ages 18 through 25, to register with the Selective Service System, whether or not a draft is active. That includes U.S. citizens (born or naturalized), lawful permanent residents, refugees, asylum seekers, undocumented immigrants, and men whose visas expired more than 30 days ago.¹ Missing the window is a federal felony on paper, but the consequences most men actually run into are civil: locked out of federal jobs, blocked from federally funded training programs, and, for immigrants, complications with naturalization.

Who Has to Register

The requirement is broad. Every male U.S. citizen and every other male person residing in the United States between 18 and 26 must register.¹ U.S. citizens living abroad are not excused. Dual nationals aren’t either, and they must register within 30 days of turning 18 no matter where they live. Male immigrants must register within 30 days of their 18th birthday, or within 30 days of arriving in the country if they enter between ages 18 and 25.

A short list of men are exempt:

Active-duty military serving full-time continuously from 18 to 26. Enlist after 18 or separate before 26, and the duty to register returns.¹
Students at U.S. service academies while enrolled.
Men on valid nonimmigrant visas (student, tourist, and similar) as long as they hold that status through age 26. Once a visa lapses by more than 30 days, the exemption disappears.
Men continuously confined to a hospital, nursing home, long-term care facility, or mental institution from before their 18th birthday until age 26, without a break of 30 days or more. The same rule covers men homebound and unable to leave without medical assistance for that entire period.²

A disability by itself is not an exemption. What matters is continuous institutionalization or being homebound for the full period from 18 to 26. A man with a disability who lives independently at any point in that window is required to register.

Moral or religious opposition to military service also doesn’t excuse registration. Conscientious objectors must register like anyone else; the registration form doesn’t even ask about beliefs. That classification only becomes relevant if a draft is activated and a registrant is called up.³

How to Register

Online registration at sss.gov is the fastest way. You submit your full legal name, date of birth, Social Security number, and mailing address, then confirm before submitting.⁴ Men without a Social Security number can register in person at a U.S. Post Office or by mailing SSS Form 1 to the Selective Service System at P.O. Box 94739, Palatine, IL 60094-4739.

You should receive a registration acknowledgment with your Selective Service number in the mail within about two weeks.² Keep it. Federal job applications and immigration paperwork sometimes ask for that number years later.

Automatic Registration Beginning December 2026

Congress enacted legislation in December 2025 that replaces self-registration with automatic registration. Under the new rule, the Director of the Selective Service System will automatically register every male citizen and male resident between 18 and 26, with no form or website visit required. The exemption for lawful nonimmigrants stays the same.⁵

The change takes effect one year after enactment, in December 2026. Until then, the old rules apply. If you turn 18 before the automatic system goes live, register yourself. A law that hasn’t taken effect yet won’t shield you from the civil consequences if you don’t.

Keeping Your Information Current and Confirming You’re Registered

Registration isn’t a one-and-done. Federal law requires you to notify the Selective Service of any address change within 10 days, and the duty continues until January 1 of the year you turn 26.⁶ Updates can be made online or by mailing SSS Form 2, which asks for your name, date of birth, Social Security number, Selective Service number, and both addresses. A legal name change requires a copy of the court order. Processing can take up to 30 days.⁷

Not sure whether you’re registered? The verification tool at sss.gov/verify returns your registration number and date if a record exists. You’ll need your last name, Social Security number, and date of birth.⁸ If nothing comes up and you think you registered, call the agency at 888-655-1825.

Criminal Penalties

Knowingly failing to register is a federal felony. The Selective Service Act sets the penalty at up to five years in prison and a fine of up to $10,000.⁹ Because the offense is a felony, the general federal sentencing statute raises the maximum fine to $250,000.¹⁰

The Department of Justice has not prosecuted anyone for failing to register since the mid-1980s. Enforcement has shifted to civil consequences, and that’s where the real cost lands.

Civil Consequences That Follow You After 26

Federal Employment

Men age 26 or older who were required to register but didn’t are barred from appointment to any executive-branch federal job. The only escape is convincing the Office of Personnel Management that the failure was not knowing or willful, and you carry the burden of proof by a preponderance of the evidence.¹¹ The hiring agency forwards your case to OPM, OPM’s decision is final with no administrative appeal, and the agency isn’t required to hold the job open while the case is reviewed.

Federal Job Training

Programs funded under the Workforce Innovation and Opportunity Act require proof of Selective Service registration as a condition of participation. Men who can’t show they registered or were exempt lose access.⁹

Naturalization

For immigrant men seeking citizenship, the impact depends on age. Applicants under 26 who refuse to register are generally ineligible for naturalization. Applicants between 26 and 31 who failed to register get a chance to show USCIS the failure wasn’t knowing or willful. After 31, the failure falls outside the statutory period for evaluating good moral character and no longer counts against the applicant.¹²

Federal Student Aid

This one used to be a major consequence and no longer is. The FAFSA Simplification Act removed the Selective Service requirement from Title IV eligibility beginning with the 2021–2022 award year. Registration status no longer affects federal grants, loans, or work-study.¹³ Some state aid programs may still require it, so check with your state agency.

If You’re Already Past 26

Once you turn 26, the system won’t accept a registration. There is no grace period and no late window. What you can do is request a Status Information Letter from the Selective Service. It can’t be requested online. You print the form, complete it, and mail it in with a written explanation of why you didn’t register, a list of every city, state, and country where you lived between 18 and 26, and supporting documents like school records, employment records, or tax returns. Send copies, never originals, and keep a set for yourself.¹⁴

The letter states whether you were required to register and, if so, that you did not. It documents the situation; it doesn’t fix it. From there, a federal employer sends the case to OPM for a knowing-and-willful determination.¹¹ Immigrant men over 31 don’t need the Status Information Letter for naturalization at all; they can print a standard form letter from the Selective Service website instead.¹⁴
