EB-1 Extraordinary Ability, Outstanding Researchers/Professors, International Managers/Executive

Under the various employment based categories, Category I based permanent residency is the most difficult to obtain. Initially, the foreign national must determine if he/she is eligible for lawful permanent residency according to the USCIS guidelines. 

An applicant filing an EB1 alien of extraordinary ability application may self-petition, but an applicant filing under outstanding researcher and/or professor and multinational manager must have a sponsoring employer.
