I'd like to see it become a state that also includes the US Virgin Islands.
Problem is that the USVI speak English while PR speaks Spanish. More realistic would be to try to merge the USVI with Florida.
Stuff can be billingual. No biggie. Not like English is universally spoken in Florida either
That wouldn't be enough for the Virgin Islanders. They get to determine their own affairs right now, but they would be vastly outvoted in Puerto Rico (or Florida, I suppose, but at least there the state legislature would speak the same language). They would never support statehood if it meant merging with Puerto Rico.
