Hello,
I had my b1/b2 application refused on 221g last October (2015). This was after I was called for an interview.
Yesterday I was asked to come for an interview again with another 221g letter forwarded to my email; I was also asked to book an appointment. I'm unable to make the appointment as the initial visa application fee is no longer valid. Would I need to make another payment on same application or is it okay to just visit the embassy with the 221g letter alone?
