Hello everyone! So I got an e-mail saying that my interview has been scheduled and I would like to know if it's possible to change my name at the day of the interview and what evidence do I need to show? I would like to change it to my married name but I still have my Social security card and work permit under my birth name. I would appreciate the help!
