Hey Alwaysme !

It's unlawful to transfer money from Nepal to USA unless it's a business transaction and is supported by Letter of Credit and other documents. There're some channels referred to HUNDI who do such business where you can deposit whatever amount you want to transfer to Nepalese agent in Nepal and receive the equaivalent dollars here from their agent here in US.

It would be better if you shed lights why you want money- for personal use, for college fee or for other business purpose. I may have more information if keep here posting.

Good luck
