Selective Service Registration and the N-400 Naturalization

Failure to register with the Selective Service System can become an issue during the N-400 naturalization process. However, there are policies and exceptions dependent on particular circumstances. Failure to register does not automatically disqualify everyone from becoming a U.S. citizen, but it can delay someone’s ability to Naturalize by a few years.
The important questions are:
- Was the applicant legally required to register?
- Was the applicant within the registration age range?
- Was the failure to register knowing and willful?
USCIS evaluates Selective Service compliance primarily in connection with the statutory requirement of demonstrating good moral character (GMC) in order to be eligible to become a US Citizen.

1. Who is required to register?
Under the Military Selective Service Act, most male U.S. citizens and male immigrants residing in the United States MUST register with Selective Service between their 18th and 26th birthdays.
This Registration requirement applies to:
- Male U.S. citizens born in the US or acquired thereafter by operation of law.
- Male Lawful permanent residents (aka green card holders).
- Male Refugees and asylees.
- Male Undocumented immigrants residing in the United States.
- Male DACA Recipients.
- Certain other male nonimmigrants who are no longer maintaining lawful nonimmigrant status (aka some visa overstays, such as Tourist Visa, Student Visa, Employment Visa, etc.).
The registration requirement generally does not apply to:
- Females.
- Men who are continuously in the United States on valid nonimmigrant status throughout the relevant period.
- Men who entered the United States after their 26th birthday.
- Men who were born before January 1, 1960.
- Certain individuals who were institutionalized or otherwise exempt during the relevant period.
2. How USCIS evaluates failure to register
The primary concern is whether the applicant knowingly and willfully failed to register.
A Naturalization Applicant generally must establish good moral character during the five years preceding the N-400 filing. There are two particularly important situations.
Scenario A: Failure to register before age 26
If the applicant failed to register but is still under age 26, the applicant should register immediately, if legally required. Recall, Male Lawful permanent residents (aka green card holders) are legally required to register.
Scenario B: Failure to register after turning 26
If the applicant is already 26 or older, registration is generally no longer possible.
USCIS may still approve naturalization if:
(a) the Applicant is now over the age of 31, as to exceed the 5-year statutory GMC Period; or
(b) the applicant establishes that the failure to register was not knowing or willful.
To be clear, between the ages of 26 and 30, N-400 Denial is 100% possible and probable if you cannot prove or convince USCIS of your knowledge or intents. The applicant should prepare a detailed explanation and supporting documentation as the applicant bears the burden of proving their knowledge and intent.
From an Immigration Attorney's perspective, between the ages of 26 and 30, N-400 shouldn't be filed in NC if someone failed to register for Selective Service due to the fact that
it is common knowledge and
a part of the NC Driver's License Process (which almost everyone has a Driver's license between the age of 18 and 26).
See the Relevant Law:

- https://ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_20/GS_20-9.2.html
3. The age of the applicant makes a significant difference
If an Applicant is under 26 years old, registration is possible to rectify this legal requirement.
If an Applicant is between the ages of 26 and 30, registration is no longer possible and the N-400 Naturalization may need to be delayed until the age of 31.
If an Applicant is 31 years old or older, an explanation can be given, and as long as other elements of Good Morale Character are met, N-400 Naturalization is possible.
Hypothetical: A 28-year-old male lawful permanent resident failed to register at age 19 may have a problem because the failure occurred within the five-year GMC period, as the male COULD HAVE REGISTERED 3 years prior when he was 25 years old.
Fast Forward: A 34-year-old male lawful permanent resident failed to register at age 19 may can overcome this problem because the failure to register occurred OUTSIDE of the five-year GMC period.
4. What documentation should be submitted if the applicant failed to register?
This is where preparation is especially important.
For an applicant who was required to register but did not, I would generally prepare the following documentation.
A. Selective Service verification (https://www.sss.gov/verify/)
Historically, USCIS instructed applicants over 26 who failed to register to obtain a Status Information Letter (SIL) from the Selective Service System.
However, effective June 30, 2026, the Selective Service System announced that it no longer issues Status Information Letters. Applicants can now check their registration information through the Selective Service verification system.
B. Applicant's sworn personal statement
A declaration by an Applicant should include:
- Date of birth (since age matters).
- The date the Applicant first entered the United States.
- The Applicant's immigration status between ages 18 and 26.
- A reason for why the Applicant failed to register.
- Any instances of when the Applicant attempted to register or otherwise resolve the matter in the past
The declaration should be specific, truthful, and supported by available evidence.
C. Immigration history documentation
Any and all immigration documents would be useful and should be included:
- Copies of all passports around and during the ages of 18 and 26.
- Entry and exit records.
- I-94 travel history.
- Copies of prior visas.
- Copies of green cards and prior immigration documents.
- USCIS approval notices.
- Evidence of any period during which the applicant maintained lawful nonimmigrant status.
This evidence is particularly important to determine whether registration was even required.
