Nepal is its own entity financially in many ways--the most obvious being how Nepali rupees being valid ONLY within the country.
I discovered another area--at least for U.S. citizens who have investments in their portfolios (including IRA accounts). Nepal is on the SEC restricted list. This applies throughout all brokerages, so if you become a resident of Nepal, your brokerage will liquidate your equities so you will have only cash in the account.
There are legal ways around this. So if you fit into this category, I suggest seeing a lawyer to figure the best way to handle this situation.
