1. High End or Needed Skills
If you have high end professional skills or fall into certain designated groups, you could get a visa from the EB series. This category is for permanent workers and is divided into five subgroups, only some of which require a pre-existing job offer.
Generally speaking, EB visas are open to people who can demonstrate an excellent level of knowledge and/or significant professional experience in their field, or who simply have skills that the US currently lacks.
