To clarify, while the FAA may not remove the night flying restriction, it is permissible for a foreign pilot who receives a U.S. pilot certificate on the basis of the person’s foreign pilot license to accomplish the required night flying training (for the appropriate grade level of U.S. pilot certificate held) from a holder of an FAA flight instructor certificate, and receive a solo endorsement to exercise night flying privileges on his/her U.S. pilot certificate.
You can either fly all night hours with an instructor or complete the FAA PPL night requirements and get a solo endorsement from an Instructor according to the above.
In addition I have called Chief Council and have left a message with the person who wrote the letter quoted earlier.
Don't hold your breath but they might call me back next week to clarify the '
of the license' and '
on the license' issue.
