Your idea is a good idea.... only if it was possible to execute. It is quite impossible to get a work permit as a pilot in the USA for what you want to do. Additionally, you could try the green card lottery (if eligible) or get married to an American and get a green card. Those are about your only options that I can think of. Someone might come up with another way but your chances of working in the US are slim to none if you aren't a citizen or greencard holder.
