From U.S. but want to study college in chennai or pretty much anywhere in TN

I am from the U.S. and always felt that India college life feels way more fun than in the U.S. I can speak good tamil without an accent and can also read and write tamil pretty fast. Whenever, I go to India people don't even realize that I am from America and they always ask me what school do I go to during my summer time (June-July). The main reason I want to move to chennai college is because I want to become an actor and a director in tamil cinema and feel like I should learn how life is out there first hand to get some experience. I have also wanted to always have friends who spoke tamil. When I told my family and friends this they are like, no you don't know life there and it'll be hell for you if you go there. Do you think I should come and will I be excluded from having friends in college?
