Let me put my opinion on this. First of all, US ma vayeka keta haru ko opinion nai kt prati naramro hunna. They want to have gf when they are in undergrad days, fall in love and when they get in better off position, they want o marry so called "pure kt" from Nepal. I have seen many of my known nepali kta doing that. Don't play blame game by trying to say that girls are chosy and want to get perfect guy. Kta haru ko tendency huncha ki they enjoy young days with girl friends, and present as sojo kta in front of they parents in nepal and marry according to their family choices. Thus it is not that girls are scare, it is that guys have to change their opinion about girls.
