The Election Commission in the Northern Marianas has mailed more than 2,100 absentee ballots to off-island voters.
The Commission's Executive Director Julita Villagomez said there were nearly 19,000 registered voters for the 6 November general elections.
The Marianas Variety reported early voting will begin 30 October.
Ms Villagomez said there will be no early voting in the Northern Islands, but commission staff will travel there on Election Day to assist.
Of the 177 Northern Island voters, only about 14 reside there.
