STEP 2: Complete the on the SSA website
Begin the process online to apply for a new or replacement Social Security card. After submitting the online application, ensure you print, annotate or take a screen shot of your confirmation number (O number). You must complete the application process by visiting your local Social Security Administration office with your confirmation number and required documentation within 45 calendar days.
STEP 3: Go to the Social Security Administration (SSA) Office
Once you have each of the documents ready and have submitted the online SSN application, you must go in person to your local SSA office with hard copy immigration documents to apply for the SSN. Be sure to take your confirmation number (O number) assigned during the online application. You may find office locations on the .

STEP 4: Wait for your Social Security card to arrive in the mail
Once your application for an SSN has been approved by the SSA, the SSA will send a Social Security card to the address you provided on your application form. The usual processing time is 2 - 4 weeks. If additional security procedures are necessary, processing times may range from 4-8 weeks. The SSA will not issue a number in advance of the card being mailed.
Most likely you will receive a Social Security card that has the notation: "Valid for work only with DHS Authorization." SSA issues this type of card to students and dependents in F-1, J-1, and J-2 immigration status because the card alone does not authorize employment.
See example:
After you receive your SSN, it’s best not to carry the card in your wallet. Instead, memorize the number, and keep the card in a safe place with your other important documents. Don’t lose your card!
