Puzzled life- I agree with Alexander that you should hang out more with American folks to improve your English. You are gonna get lot of "What's" but eventually you'll make it. You might have the same accent but they will clearly understand your english. Though you hang out with nepali people in your home/room-mate but try to make American-speaking classmate or other international students and I am pretty sure that will improve your English a lot. Also make a habit of watching English movies instead of dhoti movies. Nothing is impossible in this world. You just gotta put your effort on it.

Peace
