First of all how much experiance have you had in acting? I'm a assuming you want to do Broadway if you want to move to NYC. Do you have family or friends in NY that you could stay with to live? What paid jobs have you done? Do you already have a decent resume and head shots? Where have you studied acting? and with who? All these things are incredibly important. And since I don't know what other acting jobs you've done I can't really say if you should move to nyc or not. If you don't have much experiance definatly get some little things under your belt.
