The post-employment law applies to all employees after they leave the government.  The restrictions you face depend on your duties – what 
you work on or are responsible for when you work with the government.  There are also other factors, such as your grade level and whether 
you worked with foreign governments.  Don’t forget, certain employees face additional restrictions that are covered by rules and statutes outside 
the authority of the U.S. Office of Government Ethics.

5 C.F.R. § 2637.201(a) states:

 

Basic Prohibition of 18 U.S.C. 207(a).  No former Government employee, after terminating Government employment, shall knowingly act, as agent or attorney for, or otherwise represent any other person in any formal or informal appearance before, or with the intent to influence, make any oral or written communication on behalf of any other person (1) to the United States, (2) in connection with any particular Government matter involving a specific party, (3) in which matter such employee participated personally and substantially as a Government employee.
