However, for flying with a club or commercial operation, you need a field check out. As this will be done in a US registered 2-place trainer you will need a US pilot license. This is not true. For a field check, you are flying as a student, with the instructor in back as pilot in command. No license at all is required. By the FAA, at least. John Cochrane

If the pilot getting the field check holds the required certificate, he or she certainly could act as PIC during a field check. Many times,at our operation, field checks are done by qualified commercial pilots.
To fly solo, the subject pilot must have at least a student pilot certificate, obvioulsy endorsed by a CFI.
A foreign pilot, using a reciprocal certificate, will also need a flight review.
I guess I beat that one to death.
