The US has reduced the number of work visas for skilled high tech workers, people with master's degrees and PhDs in fields where there is a shortage, and this is for people who have found jobs with employers who are willing to go to a considerable effort and expense to hire them. So your chances of getting into the US are virtually non-existent. I, too, hate to tramp on your dreams, but I also hate to let you think that you have a chance, because you really don't.

To get in, you would need a work visa. To get a work visa, you need an employer who not only is willing to go to the effort of sponsoring you, but can prove to immigration that there are no Americans who can fill the job. Since we are in a recession, and unemployment is high, there is no reason for an employer to try, and no chance of success.

Why not look at Australia or New Zealand, where they are more welcoming. They issue visas that allow you to work and don't require that you have a job in order to immigrate. They allocate points based on things like relatives in the country, speaking English, age, and skills. There are tests on each of their immigration web sites that you can take to find out whether you qualify.

Check out the Australia forum. I think there is a sticky there, at the top, with the information you need.
