I went for adjustment of status here is US and it was very smooth. In the interview day, the INS agent asked me some questions like are you working anywhere (although I was in F1), I said yeah in on Campus and he asked me what kind of work, I said as an network troubleshooter and that was it. I received the green card in threee weeks. I think it would have been harder to do this if I had gone to Nepal. It was two years ago.
