Social Security Numbers for Immigrants and Non-Citizens
Access to a Social Security Number (SSN) is not limited to U.S. citizens — eligibility extends to specific categories of immigrants and non-citizens based on their immigration status and work authorization. This page covers who qualifies, how the application process works, the distinctions between work-authorized and non-work SSNs, and the situations in which a non-citizen may be ineligible. Understanding these rules is essential for immigrants navigating employment, banking, tax compliance, and federal benefit programs.
Definition and scope
A Social Security Number is a 9-digit identifier issued by the Social Security Administration (SSA) that tracks an individual's earnings record and determines eligibility for federal benefits. Under SSA Program Operations Manual System (POMS) RM 00203.001, non-citizens may receive an SSN if they are lawfully admitted to the United States and are authorized by the Department of Homeland Security (DHS) to work — or, in limited circumstances, if a federal statute requires an SSN for benefit receipt even without work authorization.
The SSA coordinates with U.S. Citizenship and Immigration Services (USCIS) and the Department of State to verify immigration status before issuing any SSN to a non-citizen applicant. This verification step distinguishes immigrant SSN applications from those filed by U.S.-born citizens and adds processing time that can range from 2 to 4 weeks beyond standard timelines, depending on DHS data availability.
The scope of non-citizen SSN issuance covers two broad populations: those authorized to work in the United States, and a narrowly defined group who need an SSN for non-work purposes mandated by a specific federal or state statute. For a broader orientation to how SSNs function in the federal system, the Social Security Number reference page provides foundational context.
How it works
Eligibility verification before application
Before filing an SSN application, a non-citizen must hold a valid immigration status document. Acceptable documents include a Permanent Resident Card (Form I-551), an Employment Authorization Document (Form I-766), or a visa combined with Form I-94 showing work authorization. The SSA does not process SSN applications until the applicant's immigration records are in USCIS and DHS databases, which requires waiting at least 10 days after arriving in the United States.
Application steps
- Gather required documents: proof of immigration status (e.g., Form I-94, visa, Form I-766), proof of identity (passport is preferred), and proof of age.
- Complete Form SS-5, Application for a Social Security Card, available from the SSA.
- Submit the application in person at a local SSA field office — mail-in applications are not accepted for non-citizen first-time applicants.
- The SSA transmits identity and status data to DHS for verification before issuing the number.
- The SSN card arrives by mail, typically within 2–4 weeks after DHS verification is complete.
Non-work SSN requests
A non-citizen without work authorization may still qualify for an SSN if a federal or state law requires one for benefit receipt. In this case, the SSA issues an SSN but annotates the record with "Not Valid for Employment." If work authorization is later granted, the applicant can return to the SSA with updated DHS documentation and request removal of that annotation.
Common scenarios
Permanent residents (lawful permanent residents / green card holders)
Permanent residents are authorized to work without restriction and qualify for an unrestricted SSN. They may apply at any SSA office after their green card is issued. Many apply at U.S. ports of entry through the SSA's coordinated process with USCIS, which can reduce processing time.
Non-immigrant workers (H-1B, L-1, O-1, and similar visa categories)
Holders of work-authorized non-immigrant visas — including H-1B specialty occupation workers, L-1 intracompany transferees, and O-1 extraordinary ability visa holders — are eligible for SSNs tied to their work authorization period. Their SSN remains valid beyond any single visa's expiration; the number itself is permanent, though employment eligibility may lapse if the visa is not renewed.
F-1 and J-1 students
F-1 student visa holders are not automatically work-authorized. Those with on-campus employment, Curricular Practical Training (CPT), or Optional Practical Training (OPT) authorization from their school's Designated School Official (DSO) and USCIS may apply for an SSN. J-1 exchange visitors authorized to work through their program sponsor follow a parallel process. Neither group qualifies for an SSN based solely on their student or exchange visitor status without accompanying work authorization.
Refugees, asylees, and special immigrant categories
Refugees admitted under 8 U.S.C. § 1157 and asylees granted status under 8 U.S.C. § 1158 are work-authorized upon admission or grant of status and may apply for an SSN immediately. The SSA issues SSNs to refugees through a coordinated process with the Office of Refugee Resettlement (ORR), part of the Department of Health and Human Services (HHS).
Non-citizens needing SSNs for benefits only
Certain state public assistance programs require an SSN even for recipients who are not work-authorized. In these cases, the applicant presents documentation of the specific benefit program requirement. The SSA issues an SSN annotated "Not Valid for Employment" and will not count earnings against that number.
Decision boundaries
Work-authorized vs. non-work SSN: key distinctions
| Characteristic | Work-Authorized SSN | Not Valid for Employment SSN |
|---|---|---|
| Earnings recorded | Yes | No |
| Counts toward Social Security credits | Yes | No |
| Can be upgraded later | N/A (already full) | Yes, upon proof of work authorization |
| Issued to | DHS-authorized workers, LPRs, refugees | Non-work-authorized individuals with statutory benefit need |
Non-citizens who accumulate Social Security credits through work in the United States may qualify for retirement, disability, or survivors benefits under the same rules that apply to citizens, provided they remain in a status that permits benefit receipt. Some benefit categories carry additional residence or citizenship conditions; the Social Security Benefits Overview and Social Security Eligibility Requirements pages detail those thresholds.
Totalization agreements
The United States has signed Totalization Agreements with 30 countries (SSA Totalization page) to prevent dual taxation of earnings and to allow combining work credits from both countries for benefit eligibility purposes. Non-citizens who worked in a totalization-agreement country before entering the United States may have those foreign work periods count toward U.S. benefit eligibility, even if their U.S. work history alone falls below the minimum credit threshold of 40 credits required for standard retirement benefits.
Undocumented immigrants
Individuals without lawful immigration status are not eligible for an SSN. The SSA cross-checks all non-citizen applications against DHS records, and applications without matching authorized status records are denied. An Individual Taxpayer Identification Number (ITIN), issued by the Internal Revenue Service (IRS), is available for tax filing purposes but is not a substitute for an SSN and does not confer work authorization or Social Security benefit eligibility.
Children of non-citizens
A child born in the United States to non-citizen parents is a U.S. citizen under the 14th Amendment and may receive an SSN as a citizen. A child born outside the United States who holds valid immigration status follows the same non-citizen SSN rules as adults. Parents can request an SSN for a qualifying child during the immigration admission process or subsequently at an SSA office.
Immigrants navigating these distinctions alongside questions about benefits, disability, or tax implications can find program-specific information through the Social Security Administration Overview and the comprehensive resource at the Social Security Authority home.
