I have been thinking about buying a condominium but don't have enough money for down payment in my bank here in the US.  I will need to get some money from Nepal. I am estimating around 30K USD (approx 24 lakhs NC). I know converting NC to USD is a pain in the neck and there are limitations on the amount you can carry. My question is if there are any legal ways to bring 20-30K thousand to US? Any helpful suggestion will be highly appreciated.

P.S. Illegal means will be appreciated as well
