Look at the border area of any country in this world. Forget Nepal, go to Ino Pak border, Rajasthan, LOC, I will give u a huge guard of honour if u can differentiate who is Indian and who is Pakistani, not bcoz they infiltrate but bcoz they share almost similar landscape, they share similar food, similar language and so on.

Go to Pak Afghan border, I will give u double guard of honour. People on Pak side speak Pashtoon type Urdu. Same with Afghan people. Impossible to say who is Afghan and who is Paki.

We r in US, lets look at US Mexican border, Texas, Cali, Ariz. May be all Mexican looking people are  Mexicans right????

Agreed that people infiltrate, criminals play their games, but they have this common look on both sides anywhere in the world. If Nepal India border is an exception to that, I beg pardon for my ignorance.

People look almost same on either sidesof any border region in any part of the world. The farther u go the significant the difference is. If being dark skinned is a testament to not being a Nepali then god help all of us.
