I had to get a visa under H1B, twice.I still remember the first time. It was the first visa to the USA. (as my visa had been backed by a US company and had been approved it was very unlikely it would have been denied). They took my company's letter, H1B confirmation notice, and every thing I had as eveidence of my education. I was asked why I chose to study in Moscow (USSR). The lady tried to be tough to me, but back then if I had impressed the lady probably it was because of my fluent English She asked me how many lanuguages I could speak, I said 6, fluently, and she almost jumped off her chair. They made me wait 5-6 hours inside the consulate, to the point, I was the only interviewee left there. By the time (2:00pm) I came out of the embassy with the notice to pick up the visa and passport in the evening (4:30pm) I had not eaten anything from 4 in the morning. The 2nd time, I took a new company's H1B approval notice and the gentleman asked me where else I had been after returning from the USA to Nepal for a visit (probably curious if I was a spy). I did not have to go through any hassle.
