What an Expert Opinion Letter Is and Why It Matters

An expert opinion letter is an independent professional evaluation written by a respected authority in the applicant’s field. Its primary purpose is to describe the significance of your work in terms that immigration officers—who are not specialists in every discipline—can easily understand.

A strong expert letter bridges this gap by interpreting complex contributions and validating professional influence.
