First of all It's great that you are following your interest, you should join nation school of drama in Delhi in order to pursue  a career in this field,  then(after you grow as an actor or director)  you can make you portfolio in order to apply for advertisement , modelling 

Or there special school in new york for being a director.  

At least you should try NATIONAL SCHOOL OF DRAMA,  to give yourself a chance. 

I hope to see you soon in movies. 

GOOD LUCK!!
