How to Get Your SSN as an International Student

Your Social Security Number unlocks everything in the US — banking, taxes, employment, and credit. Here's exactly how to get yours.

"Your SSN unlocks banking, credit, and your employer's payroll system — apply as soon as you're eligible."

SSN for International Students

Are you eligible right now?

F-1 students must have active work authorization before applying. Check which applies to you.

On-campus job offer
You'll need two letters: a signed offer letter from your university employer AND a separate letter from your DSO confirming your enrollment and work authorization. Both are required by the SSA. You can apply while in your first semester.
CPT authorization on your I-20
Curricular Practical Training must be endorsed on your current, valid I-20 by your DSO.
OPT / STEM OPT with EAD card approved
Your Employment Authorization Document must be physically in hand — pending applications do not qualify.
No work authorization yet
You must wait until you have one of the qualifying authorizations above before visiting the SSA.
F-1 students must have active work authorization to apply. J-1 students: check with your program sponsor — requirements vary by exchange program type.

Documents to bring

Bring originals for everything — the SSA does not accept photocopies.

Valid Passport
Must include your current US visa stamp (F-1 or J-1).
Form I-94
Print from cbp.gov before you go — bring the printed copy.
Form I-20 or DS-2019
Must show your current program dates — an expired I-20 will not be accepted.
Job Offer Letter or EAD Card
Offer letter on employer letterhead, or your physical Employment Authorization Document for OPT/CPT.
Completed Form SS-5
Download from ssa.gov and fill it out before you arrive — saves time at the office.
Optional
University Enrollment Letter
Some offices request supplementary proof of active enrollment. Ask your international student office for a dated letter.
Process
Step-by-step: getting your SSN
Follow these in order — skipping step 1 is the most common reason applications get rejected.
1
Wait at least 48 hours after reporting to your school
Your I-94 needs time to appear in federal databases. Per SSA guidance, wait at least 48 hours after checking in with your school — not just after arrival. Your university's international office can advise on their specific timeline.

2
Secure your job offer letter or EAD card
Get a signed offer letter on official employer letterhead (for on-campus work or CPT), or confirm your physical EAD card has arrived (for OPT/STEM OPT). You cannot substitute one for the other.
3
Download and complete Form SS-5
Get the form at ssa.gov. Fill it carefully — errors cause delays. Print it before you go; the office does not provide printers.
Takes about 10 minutes
4
Find your nearest SSA office
Use the locator at ssa.gov/locator. Check hours before you go — many offices close early on certain days. Urban offices often have long waits; arrive early.
5
Start your application at ssa.gov, then visit in person
As of early 2026, SSA is online-first: begin your application at ssa.gov/number-card, then visit your local SSA office within 45 days to present your original documents. Bring everything from the list above — originals only.
Start online at ssa.gov/number-card first
6
Your SSN card arrives by mail
The SSA mails your physical card to the address on your SS-5 in approximately 2 weeks. The receipt you get at the office does not include your SSN — your actual number only arrives with the card. Do not give employers a number until the card arrives.

After you receive your SSN

Three things to do as soon as you have your number.

Give it to your employer
Required for payroll, your W-4 withholding form, and I-9 employment verification.
Open or upgrade your bank account
Most banks require an SSN for full checking accounts. Use it to upgrade from a basic student account.
Start building US credit history
Apply for a secured card or become an authorized user — your SSN anchors your US credit file.

SSN vs ITIN — what's the difference?

Both are 9-digit numbers, but they serve very different purposes.

SSN
Social Security Number
  • Issued by the Social Security Administration (SSA)
  • Only for people authorized to work in the US
  • Used for employment, tax filing, and credit history
  • Required by most banks for full checking accounts
  • Permanent — yours for life, never expires or changes
Issued by: Social Security Administration
ITIN
Individual Taxpayer ID Number
  • Issued by the IRS — not the SSA
  • For tax filing only — does not authorize employment
  • Used when you have US tax obligations but no SSN
  • Accepted by some banks as an SSN alternative
  • Generally does not build US credit history, though some lenders accept ITIN applications
Issued by: Internal Revenue Service (IRS)
Protect your SSN
  • Never share your SSN over email, text, or phone — legitimate organizations use secure channels.
  • The SSA will never call threatening arrest or legal action — this is always a scam targeting international students. Hang up immediately.
  • Don't carry your SSN card in your wallet. Memorize the number and store the card somewhere safe at home.

Common questions

Is the SSN application free?
Yes, completely free. The SSA charges no fee to apply. If anyone asks you to pay for help getting an SSN, it is a scam.
Can I apply before I have a job?
Only if you already have CPT or OPT authorization. F-1 students with no active work authorization are not eligible — you must wait until a qualifying authorization is in hand.
What if my SSN takes longer than 4 weeks?
Call the SSA directly at 1-800-772-1213 (TTY 1-800-325-0778). Have your application receipt and ID ready. You can also visit your local office in person to follow up.
Do I need to update my SSN if I change schools?
No. Your SSN is permanent and stays with you regardless of school transfers, visa changes, or even becoming a US citizen. You may want to update your mailing address with the SSA, but the number itself never changes.
