At least in NJ, you can find full or part-time work pretty easy (well not so much now, but it can't stay that way forever) and plenty of bands and venues. And if you are as dedicated as you say you are, you will find a way to make it work. You would not be the first person to make this move. I know quite a few first and second generation immigrants, and usually depending on their education and work ethic the can live nicely.
