I applied a few years in a row for the american greencard. On the american government site. They have visa lottery. But I never have been choosen and last year I didnt applied. I gave up. Also Im not sure what I would do if I get it, you need to start from scratch. You do have a green card then, but you need to find a job, a house, new friends etc.
