For EB-1B, how many recommendation letters do I need?

There is no minimum number. USCIS does not set a required letter count for the EB-1B category, which covers outstanding professors and researchers. What truly matters is the quality of the letters: who signs them, how independent that person is, and how concretely they can attest to your recognition in the field.

A lean set of strong letters from respected names with specific accounts of your contributions typically carries more weight than a large stack of generic letters. The right number ultimately depends on the strength of the rest of your petition package.

• Prioritize the credibility and independence of the letter writers.
• Seek concrete accounts of your impact, not generic praise.
• Pair the letters with other evidence (publications, awards, recognized body of work).

Since there is no numerical rule, build the set that best supports your case and confirm current guidance with the official source (USCIS) or a qualified specialist.
