I am hired to become a sales team member and have gotten my orientation date. I was told to bring an ID and a SSN card. My problem is I have no SSN card, and it will take up to two weeks for it to arrive in the mail. I know my SSN by heart though but I understand they need it as proof that I can work in the United States. I was wondering if it would be ok to bring my birth certificate instead of my SSN card or if they asked for my SSN for taxes?
