Can a graduate from Trinidad become a teacher in New York?

I am a student at a university in Trinidad and Tobago that has pursued a Bachelor Degree course in primary school education. I have really dreamed of going to the United States to teach; preferably New York but I have had some negative criticisims from other people. Some of them say that the educational system over there is much harder and that there is hardly any time for vacations. There is also the problem of citenzenship and that the educational system would not hire me because of this. I have also heard that one cannot become a teacher with just a Bachelor Degree alone but I would need to get my Masters Degree which would take me two more years which I do not want to do in my country. There is also one more problem. I was on a government scholarship while doing my degree, which I am upon completion required to serve three years in my country which I really do not want to do. I have been dreaming of going to the United States for a very long time ever since I was a teenager and it is so hard. Can someone tell me is there a chance for me to do this? I am 27 by the way….
