IMHO, when the ingrates start paying all of our bills and sending us $17 BILLION dollars in cash, for every 4 million of us, each year, 10's of thousands of federal and private sector jobs, Food stamps, Welfare and $2.5 Billion dollar Urban Trains, then they can demand we speak Spanish in Puerto Rico.
You should hear some of the stories of what's happened to non-Spanish speakers that wind up in Puerto Rico's civil courts. It's the freaking 'Spanish Inquisition' all over again.
If an English speaking U.S. Taxpayer, that's had their tax dollars confiscated all their lives to support Puerto Rico while they lived stateside, moves to Puerto Rico and winds up in their civil courts for any reason, the fun starts at $75 an hour for a translator.
LOL!
