Fake documents to get US benefits is the biggest crime. Sooner or later, these people will be evaluated by Nepal government. And you can imagine consequences. No matter what, how long you have become Naturalized citizen will still be prosecuted? And later on, there won't be any place to hide. So think for a long term rather than current. It's almost a dream for most of the people especially for under developed countries to migrate and settle in US. If you are a victim then you have a right for asylum benefits. So think twice.
