regional guy,
you are correct, it's possible to work in the states if you find someone ready to sponsore you and with the approbation by the DOL (Department of labor)and the INS. A Flight instructor in the USA can log up to 2000 h of C152 and light multi-engine, and after? after everybody will laugh at you and no regional airlines will hire an european pilot cuz Regional airline pilots have Union which means:" green card or go home with your 2000h".I know what I am talking about, I have several european friends stuck in the states, making 800 US dollars per month and no futur.If it was easy, everybody would go to the states!!!
I know an airline pilot, told me one day :"I do not understand why pilots fight like this ".Apparently it's a dream job, but when you fly commercialy everyday, can be a pain in the butt to fly".
I will tell you later why there will be no job for the next 10 years.I am just worried than flight schools will try to threat me.
