Frequently asked questions
No. EB-1A is an extraordinary ability classification within EB-1. A national interest waiver is an EB-2 pathway that may waive the job offer and labor certification requirements when the legal standard is met.
Some classifications permit self-petitioning, including qualifying EB-1A and EB-2 NIW cases. Other employment categories generally depend on an employer or another qualifying petitioner.
The relationship and the petitioner’s immigration status determine the category. Family preference categories are subject to immigrant visa availability; other eligibility rules also apply.
Eligible applicants may seek adjustment of status in the United States or pursue immigrant visa processing abroad. The correct route depends on the category, immigration history and eligibility.
No. Petition approval and becoming a permanent resident are different steps. Visa availability, admissibility and a qualifying adjustment or immigrant visa process may still be required.
PERM is an employer labor certification procedure required for many, but not all, employment-based immigrant petitions. It is not a separate immigrant visa category.
Schedule A provides special labor certification procedures for specified occupations, including certain professional nurses and physical therapists. Petition and immigrant visa requirements still apply.
Potentially. Each has separate requirements for obtaining the initial protection or status and for later adjustment. Grant of the initial benefit is not itself a green card.
