Sponsored my parents from Iran, waited for 2 years in AP and finally got an email for them saying to go to embassy, submit passport new medical and 2018 tax return for my family. I am aware of travel ban and actually had my us seantor and house rep to contatc embassy on my behalf. Was wondering are my parents pssport get a visa stamped on and have they recieved a travel ban waiver. Also in the email it said passport will be returned no sooner than a week. I am really nervous and really want them to get out of the country. If they are not gone issue a visa why would they ask to submit passport?
