U got me there, on the serious note, U can travel around with 10k in US. Nepal govt doesnt really care about how much cash u bringin. I have taken up to 15k in cash one time. Is anyone travelling with u? Otherwise u can just split the cash with them at the security check point. That is the only place where they may find out how much u got? But most likely they shouldnt make big deal out of it. just put lik 7k in ur one pocke and the other 7k in another one..im sure they will not sit there and count ur cash.
