Non-voting members of the United States House of Representatives include non-voting delegates and resident commissioners. They are non-voting members who are elected from a U.S. territory or from Washington, D.C., to a two-year term (with the exception of the one representing Puerto Rico, who is elected to a four-year term). While unable to vote in the full House, a non-voting member may vote in a House committee of which the delegate is a member, as well as introduce legislation. There are currently six non-voting members, representing Washington, D.C., Puerto Rico, American Samoa, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands.
