The Coast Guard Personnel Manual, Chapter 12, contains information on retired members' obligations. Paragraph 12.C.18.f outlines requirements for retirees to request permission to seek employment with a foreign government.
Retired members contemplating employment by a foreign government or a company
owned by a foreign government must submit a written request to
(CG-122), for retired regular members, or
Commandant (CG-131) for retired
Reservists, before accepting such employment. The request process and
information required are described in Chapter 16.L.
In order for the Coast Guard to process the request with the State Department you must submit a letter including the following information:
Commandant (CG-122) or (CG-131) will provide a cover letter and submit your request to the U.S. State Department, Foreign Employment Office. The Coast Guard will directly provide the requestor with the State Department's response.
