What do I need to emigrate to the United States?

I really don't know, but you have a higher chance of starting a life out here if you get your degree out here. So maybe try getting a doctorate in the U.S? First of all, what kind of jobs are you applying for? Maybe you should start at the bottom, applying for jobs in America that aren't exactly related to your degrees. And then, think about it, American companies aren't gonna hire someone who lives in Ireland and has lived in Ireland their entire life for their company and ume just because I hire them that they'll automatically be able to begin this job. Do you have the money to come here? It takes years to get visas and junk. You should also establish residency here as well, by perhaps living here for a while... It's not easy okay? Don't expect it to happen right away, it WILL take time. Don't give up.
