Workers who go abroad to work through labor export really can't get a green card and can't immigrate?

Those who export labor services can't get a green card, which means that they used to work and have to return to China after working, because the qualification of labor service companies is only labor export. If you want to immigrate after working abroad, you should find an immigration company with immigration qualifications. Please contact me at Baidu to help you solve the problem you want.
