you dont. the only Id u have right now(i assume) is your passport and that’s what you will include(foreign passport is also valid document in US) . SSN unfortunately you cannot get trough k1 unless you applied and got work permit trough it. if u did than that can serve you as ID and ID to get ssn, if not youll have to wait until you get work permit to apply. usually in i485 form theres a question do you need ssn? so usually they send you Ssn after they send work permit but if it doesn’t come within a week just go to your social security office and apply for it yourself. thats what i did. i hope this helped you a little bit. good luck

Thank you! work permit now takes very long to get approved. so how I gen be added to my husband insurance and taxes or anything else that requires SSN?
