Only US operators (121, 125, 135, 91k and some straight 91) are required to submit reports under part 111, the PRD. So there probably won’t be anything about a foreign pilot. Part 111 does say -
Reviewing entities may allow an individual to begin service as a pilot without first evaluating records in accordance with
§111.105 only if the reviewing entity—
(a) Made a documented, good faith attempt to access all necessary information maintained in the PRD that the reviewing entity is required to evaluate; and
(b) Received notice from the Administrator that information is missing from the PRD pertaining to the individual’s employment history as a pilot.
So they have to ask and be told there are no records on that pilot.
