The EB1 visa is a preference category for United States employment-based permanent residency. It is intended for “priority workers”.
Those are foreign or “alien” nationals who either have “extraordinary abilities”, or are “outstanding professors or researchers”, and also includes “some executives and managers of foreign companies who are transferred to the US”.
It allows them to remain permanently in the US. https://en.wikipedia.org/wiki/EB-1_visa
The EB-1 is the best and most desirable among all the other Employment-based Visas.
It offers the quickest path to U.S. permanent residency, as it does not require the filing of a Permanent Labor Certification, usually a time-consuming and expensive process.
In addition, visa numbers are always current for the EB-1 application category, so you will not have to wait before applying for Adjustment of Status and receiving a Green Card.
Furthermore, the applicant can file other immigration petitions under other appropriate categories (such as a National Interest Waiver) while an EB-1 petition is pending.
There are three categories of people that qualify for the EB-1 visa:
– Workers of Extraordinary Ability (EB-1A)
– Outstanding Researchers or Professors (EB-1B)
– Multinational Managers or Executives (EB-1C)
