Legality is a gray area in Nepal when it comes to foreign currency. Buying dollars from bank can be a hassles. But if you can a credit card, you can draw in travelers checks. Otherwise, you can easily buy dollars at money exchange places at slightly higher than the bank rate. It also depends on amount and intended purpose. Why you want to buy dollars in Nepal. Although legally not permissible, I know people who have brought in more than 50K cash, and I have not known case where people have been busted for bring in dollars. Few have been questioned and detained for bring in Indian currency because of rampant circulation of fake IC and other illegal cross border activities. PrivateEyeNepal@gmail.com
