PERM is loosely the beginning of the process of employers filing for green cards for their foriegn workers. These are primarily for H1Bs who have been working in the company for up to 6 years. Contrary to popular belief, employers don’t have to seek Americans first when looking to fill a position with an H1B. Six years later, when they want to begin the green card process for the foreign worker, that’s when they need to advertize......a rather stupid thing if you ask me, because in reality, there’s really no open position - since someone’s been working in the position for the past 6 years. It results in wasting everyone’s time, and finding ways of going round the law as evidenced by this video.
If you ask me, I'd say something stronger than that. Thanks for the info.
