EB1A Independent Expert Letters: Use Outside Researchers to Explain Actual Impact
An independent expert letter can be useful when the writer has a credible professional basis for knowing the applicant's work. The strongest letters explain concrete facts such as citation, adoption, implementation or influence and connect those facts to objective documentation. Independence alone does not make a generic letter persuasive.
Independent Knowledge
The Writer Should Have a Real Basis for the Opinion
Method User
Can document independent use of a technique or methodology.
Technology User
Can explain implementation of software, devices or technical work.
Field Expert
Can provide field context when the basis of knowledge is specific.
Evidence File
Documents That Strengthen an Independent Expert Letter

Technical Documentation Corroborates use of the work.
Writer Biography Establishes relevant expertise.
Publication Record Supports the writer's professional qualifications.

Common Mistake
A Famous Stranger Is Not Automatically a Strong Expert
Weak
A prominent professor reads the applicant's CV and signs a generic letter.
Prestige does not create personal knowledge of the applicant's research impact.
Stronger
Use a researcher who actually encountered the work.
A less famous expert who cited, adopted or used the contribution may provide substantially stronger factual evidence.
