Currently I’m in US visa obtaining process. I applied via Pony Express on 16th of May and on 28th of May I had an interview in the embassy. After passing of several security barriers I was invited for the fingerprinting procedure. Need to state that there were a lot of people and we were gathering into short queues at each step (security, fingerprinting and interview). After leaving the copy of my finger patterns in the data storage of US embassy, I was invited to the window to be interviewed. Mid-aged woman, asked me several questions, and said that because I’m software developer, and moreover I've got some previous experience in AI, I need to be checked more carefully and hence I need to present my CV and the list of my publications to them. I thought to do so, but I don’t know why I didn’t. In short she gave me the fax number and e-mail address, to send them these papers. I did it at the same day. But today they’ve called me and said that they need my invitation letter from MS (I don’t know why, the consular officer returned it to me), so they requested to send it by fax. Also they insisted not to order tickets before they make any decision. Now I understand how it difficult to issue US visa. Allah, help me please.
