I am not the student at Cornell. Currently I am a PhD student in some reputed university in USA. Based on my experience, it is hard to get funding for MS program. The reason is that ECE program at Cornell is competitive and many good students from India and China (from IIT and Tshingua) apply for PhD program. I am not trying to discourage you, but let you know what I experienced. I managed to get funding for my MS program with some really hard work.

If you decide to join Cornell without funding, let me advice you. Professors want free students. Find out a professor with good funding history and volunteer for free. Work hard and they will fund you if you perform well. Since you got admitted to Cornell, you must be a smart guy. Good luck!!
