It's not really practical to move to the US on an EB-2/EB-3 green card since even at best its an 18 month process if you're not from one of the countries that reached its per country limit, so you're unlikely to find an employer to sponsor you to start a job so far in the future. So usually what happens is you move over on an H-1B but those are subject to an annual cap for which you only have a 1/4 chance of being selected unless you work for a cap-exempt non-profit employer. Employers will usually sponsor a green card after you start working for them.
