Area 51 in Crystal Springs, Nevada
The people of Puerto Rico have narrowly rejected statehood in plebiscite elections on three separate occasions since 1967. There may be a fourth Plebiscite in 2012 if the current governor gets certain legislation passed. In order for a territory to become a state of the United States 5 things have to happen. 1) The territory has to have a constitution (Puerto Rico Has one of these) 2) The voting public of the territory must vote to ask for statehood. 50%+1 of the electorate must vote to request statehood. 3) The territory has to petition Congress (US House and Senate) to be accepted into the Union. 4) Congress (both houses) must pass a resolution accepting the Territory as a state. 5) The President of the United State must "certify" Statehood (sign the Congressional Resolution into Law)
