Puerto Rico's representative in Congress is seeking an unprecedented yes-or-no vote on whether the island should become the 51st state, a bill that is riling many in the U.S. territory.

The bill that Pedro Pierluisi filed Wednesday calls for a federally approved ratification vote in which Puerto Ricans would be asked if they want their island to become a state. If the majority agrees, the bill calls for the president to submit legislation to Congress within 180 days.

Pierluisi's bill comes a month after the White House announced it would seek $2.5 million from Congress to fund a vote on the island's future political status.

There has been no agreement on the meaning of the results of a nonbinding referendum in November.
