Hi guys I need your suggestion about graduate college in US. My brother wants to come to US, he has completed his undergraduate in computer science from Nepal and now asking me to look for college here. Is it hard to get visa with IT major for graduate? If so what would be his options? Also if you know any graduate schools, please suggest. Thank you

Please be specific to your question.
Nobody can tell you how hard or easy it would be to get US visa for IT major graduates.
http://usefnepal.org/ would be one of the place to start for looking for colleges.

Its the perfect time to apply.
1) First get GRE exam done with excellent score,
2) Start looking for Graduate schools with graduate assistantship (GA) or teaching assistant (TA).
3) Prepare your portfolio with your achievements, recommendations, and future goals.
4) Contact schools directly. I see very bright future for computer science graduates.
