Have you change your name or became a U.S. citizen?
I did become a U.S. citizen, yes.
then you should inform Social Security so your records can be updated and you can get issued a new card.
I don't have permission to work.
As a lawfully admitted noncitizen, you still have many benefits without having a social security number. You can do business with a bank, obatin private health insurance, apply for educational test, etc.
tell me abbout M-1 students.
for M-1 students, they need to show Social Security their I-20 Certificate of Eligibility for Nonimmigrant Student Status to show their immigration status.
Let me ask you again about what I can do without a social security number. If I need to get a driver's license, can I actually get a social security number?
no, if that's your only purpose for asking a social security number, then no, you can't.
In case I change my name, do I have to inform my employers?
