sometimes you have to be a friend to make a friend... if that makes any sense.  Try getting to know the people that you are socializing, studying with ... what interests them, their values, etc. and start conversing and planning things around that to build your network of friends, if you're comfortable with doing that. Partake in activities where you get to meet people, assuming you're in college, there are lots of opportunities to do that. But remember that it's a 2 way street. Also, i don't think that the definition of friends includes having to be a nepali, while yes that might be your comfort zone, remember that you're not in Nepal anymore. I have friends from different cultures and I've been surprised by how supporting they can be. Don't limit yourself.

Also, no one can ever have enough friends, albeit true friendships are rare.
