To apply for a Social Security number on a K-1 visa, wait about 10 to 14 days after you enter the United States, then visit a Social Security office in person with your unexpired passport (containing the K-1 visa), your printed I-94 arrival record, and a completed Form SS-5. K-1 entrants are classified as work-authorized on arrival, so no separate work permit is needed to apply.1eCFR. 8 CFR 274a.12 – Classes of Aliens Authorized to Accept Employment The catch is timing: your 90-day admission sets a hard back-end deadline, and applying too early can fail verification.
When to Apply
Don’t walk into a Social Security office the day after you land. Customs and Border Protection creates your electronic I-94 at entry, but that record has to propagate through federal systems before the SSA can verify it. The agency checks your status through an interagency database called SAVE, and if your arrival data hasn’t synced yet, the check either fails or gets pushed to manual review.2U.S. Citizenship and Immigration Services. SAVE Waiting 10 to 14 days after crossing the border gives the systems time to catch up.
The other end of the window is just as important. The SSA generally won’t process a K-1 based application if your I-94 expires within 14 days, because the agency needs time to complete verification before your authorized stay ends. Since K-1 status runs exactly 90 days, that pushes the practical cutoff to around day 76 after arrival. Miss it and you’ll have to pursue an SSN through the adjustment-of-status process, which takes longer and costs money. The safe window sits between roughly two weeks and two months after arrival.
If SAVE Verification Stalls
Most SAVE checks resolve in seconds. When they don’t, the case moves to manual review, which as of March 2026 takes about 18 federal workdays.3U.S. Citizenship and Immigration Services. SAVE Verification Response Time That’s close to four calendar weeks, and it eats into your 90-day window fast. Applying earlier in your stay gives you room to absorb that delay. If your I-94 has an error in your name, birth date, or passport number, CBP’s customer service line at 1-877-227-5511 can help correct it.
Documents You Need
Federal rules require convincing evidence of your age, identity, and immigration status for a first-time SSN.4eCFR. 20 CFR 422.107 – Evidence Requirements For a K-1 holder, that comes down to two things:
- Your unexpired foreign passport with the K-1 visa stamp inside. It proves both identity and age.
- A printed copy of your I-94, downloaded from i94.cbp.dhs.gov. Enter your name, date of birth, and passport number exactly as they appeared on the travel document you used at entry.5Homeland Security. I-94/I-95 Frequently Asked Questions
Everything must be original or certified by the issuing agency. The SSA will not accept photocopies or notarized copies.6Social Security Administration. Application for Social Security Card Form SS-5 Documents in a language other than English need a certified English translation, with the translator’s signed statement of competence and accuracy.
Filling Out Form SS-5
Form SS-5 is the standard application. Download it from ssa.gov or pick one up at any office. Two fields cause most of the trouble. Enter your name exactly as it appears on your passport; small discrepancies here cause problems later with employers and background checks. For citizenship status, select “Legal alien allowed to work.” The rest is straightforward demographic information.
How the Office Visit Works
You can start the application online at ssa.gov, but you still have to appear in person to present original documents.7Social Security Administration. Request Social Security Number for the First Time Starting online shortens the office visit because some of your information is already in the system. Use the SSA office locator to find the nearest branch and plan for a short interview.
At the office, the representative runs your information through SAVE to confirm your K-1 status with the Department of Homeland Security. If the check clears, your application moves to final processing, and the card generally arrives by mail within 7 to 10 business days after the SSA has everything it needs.8Social Security Administration. How Long Will It Take to Get a Social Security Card? Add a couple of weeks if your documents get flagged for extra verification.
What Your Card Will Say
The card you get won’t be an unrestricted one. It carries the printed legend “VALID FOR WORK ONLY WITH DHS AUTHORIZATION,” signaling that your right to work depends on keeping valid immigration status.9Social Security Administration. Types of Social Security Cards The number itself is permanent. The restriction is on the card, not the number, and it reflects your temporary K-1 status.
After you adjust status and receive a green card, you can visit a Social Security office with your Permanent Resident Card and birth certificate to get an updated card without the legend.10Social Security Administration. Apply for Your Social Security Card While Applying for Your Work Permit and/or Lawful Permanent Residency Replacement cards are free and typically arrive within two weeks.
If You Miss the 90-Day Window
If you don’t apply before the K-1 cutoff, or if verification delays push you past it, you can no longer get an SSN based on K-1 status alone. Your path shifts to adjustment of status. After marrying your U.S. citizen sponsor, you’ll file Form I-485 to adjust to permanent residence, and you can also file Form I-765 for a work permit while the I-485 is pending.
Both forms include a checkbox to request a Social Security number directly, which authorizes USCIS to share your data with the SSA. No separate office visit is needed once the application is approved.10Social Security Administration. Apply for Your Social Security Card While Applying for Your Work Permit and/or Lawful Permanent Residency After approval of either the work permit or the green card, the SSA issues your card within 7 to 10 business days.8Social Security Administration. How Long Will It Take to Get a Social Security Card?
This route isn’t free. When Form I-765 is filed with Form I-485, the I-765 carries a reduced fee of $260.11U.S. Citizenship and Immigration Services. Frequently Asked Questions on the USCIS Fee Rule The I-485 has its own separate fee, and biometrics stack on top. Applying during the K-1 window, when the SSN itself is free, saves real money.
Updating Your Name After Marriage
Most K-1 holders marry within the 90-day window, and many change their surname. If your legal name changes, update your Social Security record to match, or the mismatch between your passport name and your married name will cause trouble with employers, banks, and tax filings.
To update, bring evidence of the name change along with your identity and immigration documents. A marriage certificate is the standard proof, and it must be an original or a certified copy from the issuing authority.12Social Security Administration. Learn What Documents You Will Need to Get a Social Security Card A foreign-language certificate needs a certified translation.
You can start online or schedule an appointment at your local office.13Social Security Administration. How Do I Change or Correct My Name on My Social Security Number Card? If the name change happened more than two years ago, the SSA may also ask for an identity document in your prior name, so handling it soon after the wedding avoids extra paperwork. Replacement cards are free and arrive within 5 to 10 business days.14Social Security Administration. Replace Social Security Card
If Tax Season Arrives Before Your Card
If April comes and the card still hasn’t shown up, you have options. Request an automatic filing extension with Form 4868, which pushes your filing deadline to October 15. You don’t need an SSN or ITIN to file the extension; write “ITIN TO BE REQUESTED” in the identification number field.15Internal Revenue Service. Individual Taxpayer Identification Number (ITIN) The extension only covers filing. If you owe taxes, payment is still due by the original April deadline.
If you expect long delays, you can apply for an ITIN by submitting Form W-7 with your tax return. Once your SSN arrives, use it going forward, and the IRS can merge the records. For couples filing jointly where the U.S. citizen spouse already has an SSN, a tax professional can help you avoid mismatched identification numbers across returns.
