I am working in the US on H-1B and went to Canada for visa application but
got checked. The interviewer returned my passport to me and told me I could
go anywhere except the US. If I go to China now, how can I get a visa
attached passport to return to the USÉ Do I need to mail the passport
back to consulate and get the visa stamp attached when it is ready or I
have to go to the consulate by myselfÉ
Thanks!
