The House of Representatives passed legislation that would allow Puerto Rico full independence, although that is a very slight possibility indeed.
The Puerto Rico Status Act allows a referendum vote with three options: full independence, U.S. statehood or sovereignty with U.S. association. The House of Representatives passed this act but it does not have a great chance of passing the Senate. Republicans say that they do not favor the bill because it does not have a fourth option, namely, to keep Puerto Rico as it is, a freely associated territory.
Currently, Puerto Ricans are US Citizens but they do not have the right to vote in national elections. They DO have the privilege of paying federal taxes and sending their children to war though. Is that a good deal?
