PhD Green Card

Green Card

Research Based Permanent Residence

Green Card Options for Researchers, Scientists and PhD Professionals

Researchers pursuing permanent residence often evaluate three employment based classifications: EB1A extraordinary ability, EB1B outstanding professor or researcher, and EB2 National Interest Waiver. The categories can rely on overlapping research evidence, but their legal structures are different. The strongest strategy starts by selecting the right category before assembling exhibits.

Three Research Categories

Choose the Legal Framework That Fits the Researcher

EB1A

Extraordinary Ability

Self petition classification focused on extraordinary achievement and sustained acclaim.

EB1B

Outstanding Professor or Researcher

Employer petition requiring qualifying employment, experience and international recognition.

EB2 NIW

National Interest Waiver

Self petition option requiring underlying EB2 eligibility and satisfaction of the NIW framework.

Evidence File

Research Evidence That Can Matter Across Categories

Publications Scholarly research output.
Citations Independent scholarly influence.
Peer Review Judging the work of other researchers.
Original Contributions Important research advances.
Patents Technical inventions and implementation.
Research Grants Funding, progress and resources.
Critical Roles Important organizational responsibility.
Recommendation Letters Specific expert explanation of technical facts.
Common Mistake

Do Not Treat EB1A, EB1B and NIW as Three Difficulty Levels of the Same Petition

Weak

NIW is easier EB1A and EB1B is employer sponsored EB1A.

The categories contain materially different legal elements and petition structures.

Stronger

Analyze each category under its own requirements.

Use the same research evidence differently depending on the legal question it is intended to answer.
