the big companies only recruit the best top 20 Computer Science university students This is not true. Source: I'm not a 'top 20 Computer Science student' and just signed my offer at a major company. My advice would be to find a professor at your university who's research and attitude you admire. Talk to him/her about your goals of doing an internship in the US and don't be shy to show some enthusiasm. Show that you're willing work hard. If you build up a good relationship with the professor, he/she will likely introduce you to some contacts. Find a good balance between not being too picky on the position or just blatantly accepting anything. Good luck!
