Asim,

First of, I'm so sorry to hear that! Nowadays,  I heard that they're making it strict than before. I heard too many Indians stuck in India apparently for background check. It even happened to two of my friends back in 2006/7 and took about 6 months to finish their process. One of them had the matching name with some other guy who had some problem, I guess. It was really unfortunate for him. Other guy had some issues with his studies and some police records.

So, when did you get that form and did you ask them what was the reason? Also, you need to keep calling them to follow-up on your case. Don't expect them to call you. Other than that, I've nothing else to suggest. I am also planning to visit Nepal and now have to think twice. Please keep posted!

Best of luck!
