With two different opinions I'm still in a dilema, though I'm inclined towards letting them know the facts, I don't rule out offline's suggestion. Anyway, thanks guys for letting me know your experience. If there are more Nepalese with similar experience, I'd be happy to hear. And Jayamatadi congrats and all the best to you. Let us know when you get your green card. Thanks everyone for replying and I hope more will discuss on this topic because I think it is a common choice most make.
