Do recommendation letters for the O-1 have an expiration date?

There is no formal expiration date for recommendation letters in the O-1. They do not expire on a fixed date, but they must currently reflect the recognition your work has received.

In the O-1, recommendation letters are not a standalone requirement: they carry real value when written by renowned experts who know your work and describe, concretely, your contributions and the impact you have made in the field.

• The weight comes from the quality and relevance of who signs, not from a date.
• Recent letters tend to better reflect your current recognition.
• They add strength when accompanied by other robust evidence of excellence.

Since each case is evaluated as a whole, it is worth keeping your letters aligned with your current trajectory and checking the latest guidance from USCIS or with a specialist.
