I used moneygram. MoneyGram is avialable everywhere in USA and Nepal. Don't need to deal with SSN. Money can be collected in Nepal in 10 mins and their fee is like mucha or moneytonepal.com. Before I have used moneytonepal, thamel.com, direct bank wire transfer but not finally I started using moneygram for its fast transfer. I paid like $12 for $1000 transfer to Nepal via moneygram. Only catch with moneygram is you have to pay Cash while transferring with moneygram.
