I can help you with that. You can replace your card for free if it is lost or stolen, however if you know your Social Security number you may not need to get a replacement card.
Do you need a Social Security number for reasons that do not relate to not having permission to work?
No, not an issue for me.
Do I need a card to register for school?
No, you don't need a Social Security card to register for school.
But, what if I am an F-1 student authorized to work in curricular practical training?
You will need to provide us your Form I-20 with the employment page completed and signed by your designated school official.
What if I use it to work?
If you use it to work, we will inform DHS.
What documents do I need to provide to prove my US immigration status?
