Guys,
The title is little misleading, and I apologize.
I need your suggestions here.
My questions:

1: If we are traveling to Nepal, how much money can we carry with us?

2: If I dont want to carry the cash, what are my options? (I heard they don't accept american express travelers check no more)

3: If I plan to bank some money back home, how can I get a tax statement for filing here in the USA as foreign investment?

thanks in advance!
