@Happysharma: Sab_nepaliko_sathi is absolutely right and spot on.

However, one of the employees of our company who was on contract through consultancy has been still stuck in india although letters were provided from the main company. She went there like 3 months ago but hasn't come yet. Don't know what happened?

But it may be different scenario too. It depends upon the mood of counselor you know. so if it's an emergency give it a shot and let me know coz i'm also planning to go to nepal and come back as i am also an contratual employee through consultancy.

Please share your experiences though either by mail or through sajha.

Good luck.
