I'm not sure what kind of Carribbean medical school the OP went to, but based on the information that he provided us, it doesn't sound very reputable. For one, he hasn't taken the boards yet or passed it, even though he already graduated from medical school. Second, he doesn't seem to have received any form of advising from his medical school, because if he did, he would know how competitive ophthalmology is and how notoriously difficult it is for foreign medical school graduates to match into the program. Apart from that, what kind of medical school would graduate someone who hasn't done any kind of rotations (or let him work as an ophthalmology tech while attending school)? This all sounds very questionable.
I don't want to rain on anyone's parade, but unless the OP graduated from one of the Big four Carribbean medical school (SGU, Ross, AUC, and SABA) that's accredited in all US states, it doesn't sound very possible that he'll be able to match into a program. Part of that has to do with competitiveness (there are already a lot of competitive US medical school applicants who are applying to the program). Another is the fact that these programs are not FMG friendly. But for the OP, I think the biggest problem is the fact that he graduated from a Carrribbean medical school that might not be accredited. I certainly hope that's not the case, but until the OP tells us which school he graduated from, I would say that ophthalmology is probably not the field that he should be aiming for at this point.
