For EB-1B, there is no fixed number of institutions to contact or recommendation letters required by USCIS. What matters is the strength and diversity of the evidence, not an exact count.
In practice, a common recommendation strategy combines distinct sources:
- Letters from within your own institution, attesting to your performance and results.
- Letters from independent experts, with no employment relationship with you, from other recognized academic entities in your field.
More than the number, what carries weight is the quality of each letter: it should concretely describe your contributions, the impact of your work, and what sets you apart from other professionals in the field. Generic letters add little value.
Since the criteria are evaluated on a case-by-case basis, it is worth checking the updated guidelines on the official source (USCIS) or with a specialist to put together a consistent set of letters.
