Sunday, Oct. 8, is the last day District residents can register to vote in the Nov. 7 general election.

To be eligible to vote here, applicants must be U.S. citizens who are at least 18 years old by Nov. 7, and residents of the District for at least 30 days before the election. They may not claim voting residence or right to vote in any state or territory. Those who have not voted here in the past four years must re-register to vote in the general election.

Prospective voters may register in person at the Board of Supervisors of Elections office, in Room 7 of the District Building, today and Friday, 8:30 a.m. to 5 p.m., and Saturday and Sunday, 9 a.m. to 5 p.m.

Registration also is taken by mail. Forms are available at all District public libraries and from various civic groups. Mail registrations must be postmarked no later than Oct. 8.

People who will not be in the District on election day and those who are unable to go to the polling place in their precinct because of their physical condition may vote by absentee ballot.

An absentee ballot for the Nov. 7 election may be requested by mail, providing the request reaches the board of elections no later than Tuesday, Oct. 31. An absentee ballot also may be obtained by appearing in person in Room 7 of the District Building and making a written request no later than 5 p.m., Friday, Nov. 3.

To be counted, a mailed absentee ballot must be postmarked no later than midnight, Nov. 7, and received by the board of elections no later than six days after the election. A voter also may cast an absentee ballot by bringing it to the precinct or to the board's office by 8 p.m., Nov. 7. A person who is mailed or handed an absentee ballot may vote in the election only by that ballot.
