I am male. But the green card said I am Female.
After you get the receipt, the local office will give you a stamp, is this true?
I tried to get the stamp with the green card copy, the original already send back to USCIS, but they refuse
to give me stamp. They said I have to wait for the card. And they do not care if I have to travel.
