Section 11-208. Special federal voters; cancellation of registration

1.
  Voters registered pursuant to this title shall be eligible  to  vote  in
  every  election  in  which  special  federal voters are eligible to vote
  which is held on or after the  thirtieth  day  after  receipt  of  their
  applications for such registration.
    2.    If  any ballot, application form or other mail sent to a special
  federal voter at his address outside the United States by such board  is
  returned  by  the  post  office as undeliverable, the board of elections
  shall send a confirmation notice to such special federal voter  at  such
  address  pursuant to the provisions of section 5-712 of this chapter and
  shall place the registration of such voter in inactive  status.  If  the
  board of elections subsequently receives notice of a new address outside
  the  United  States for such voter, or notice that the voter is still at
  the same address outside the United States, the board shall restore  the
  registration  of such voter to active status in the manner prescribed by
  section 5-213 of this chapter.
    3. The board of elections shall process and preserve  the  records  of
  such   registrations,  including  the  original  applications  for  such
  registrations, in the same manner and for the same period of time as the
  records  of   other   voters   registered   under   permanent   personal
  registration.
    4. A special federal voter whose registration is cancelled pursuant to
  the  provisions  of  section  5-400 of this chapter shall be eligible to
  reregister in the manner provided by this title.
    5. Upon  cancelling  the  registration  of  a  special  federal  voter
  pursuant  to  the provisions of section 5-400 of this chapter, the board
  of elections shall forthwith notify  such  voter  at  his  last  address
  outside  the  United  States of the fact of the cancellation, the reason
  therefor, and of his right to reregister pursuant to this title.
