Commander,
You wont get a dispatch job with an airline over there unless you have a FAA license, it really is as simple as that.
If I were you I would start looking at some schools over there and try to get an idea of what a Flight Dispatcher does, Try a google search for 'FAR part 65, subpart C' and look for Dispatcher.
There are various posts on here about the difference between Ramp Dispatcher in the UK and Flight Dispatcher in the US, pretty much the only thing they have in common is the name 'Dispatcher' they are two different jobs....
On another note, health insurance can be quite expensive if you had to get it yourself, most employers do offer some kind of medical cover though...
