[A2A] I would seriously advise against it. My friend was once scolded by a professor in Stanford after he got admitted into MS and he was calling for funding opportunity.
Already, many professors in US are annoyed by many emails that they get from Indian students asking for internship opportunities. I also get so many emails (average 1 per day) when I am in IIT Roorkee, I can only imagine how many emails professors would be getting in universities like Stanford. You can do whatever you want, but I don't think much good can come out of calling a professor whom you do not know.
I like to blog about various topics ranging from education in IITs to social issues in India and US. All opinions and views presented here are my own and not of my employer.
