Document:
If you moved to Rhode Island from another state, you must register to vote in Rhode Island to be able to vote. The last day to register in time to vote in the next election is thirty days before the election.
I moved within Rhode Island.
Many registered Rhode Island voters who move are still entitled to cast a ballot that will be counted — even if they did not notify the appropriate election official about the move before Election Day.
If you moved to a new address that is covered by the same polling place as your old address, you can vote at that polling place or at your local board of canvassers after filling out a written change of address form. This is true regardless of how close to the election you moved.
If you moved to a new address in a different polling place within the same city or town, 30 days or more before an election, you can vote a full ballot at the polling place for your new address or at the local board of canvassers after filling out a written change of address form.
If you moved to a new address in a different polling place within the same city or town, less than 30 days before an election, you can vote a full ballot at the polling place associated with your old address or the local board of canvassers after filling out a written change of address form.
If you moved to a new address that is in a different city or town within the state less than 30 days before an election, you can vote in your old city or town.
If you moved to a new address that is in a different city or town within the state less than six months before the next election, but do not register in your new city or town, you can vote a limited ballot from the board of canvassers of your former city or town.
