euta_ nepali : this is like a random check .. but too often n too frequent .. also depends upon which route ur using to check in airport...if u r coming through china/ turkey/ route they go more into ur hand carry n luggage.. koz these are the people who come from usa/ japan/australia...they know these people have more money ( without declaration ), expensive gifts ( phones, liquors ) etc .. when caught the process is so tedious n expensive that u eventually give up those items

if u come from gulf route ( our fellow gulf workers route) , they treat u even worse, rude ( most of the gold smogling takes place from this route ).. taking 2 3k dollars is not a big deal u dnt even need any proof (provided u have us visa/ us passport )..if ur on b1 category n hold more than 3 thousand dont do it ...i am supposed to take back 20 K $ (cash) but not been able to...

the reason behind doing this is nepal is under severe financial crisis n nepal government, finance minister ( yubaraj khatiwoda ) trying his best to seal revenue leakage
