Like others said, moving through employment would be the most straightforward way. I actually moved TO the US instead of from, and I did so by asking my employer to relocate me. It was still tough, but because I was sponsored by my job, I had a lot of support (immigration lawyer and relocation costs paid for). The most ideal way is to get employed in the US by a company that has an office in your desired country. Then try to get moved there via internal transfer. The next option is apply for jobs in the desired country that are willing to sponsor you, but that’s harder because not a lot of local companies are willing to spend. The first one also allows you to hit the ground running.
