most states and/or some counties have official languages. it's just not regulated on a federal level.
i guess it's just a matter of time before it's established as a federal law.
city above, idk, i'm a bit rusty. i'll go with plovdiv. it looks smaller than plovdiv though.
Well there have been amendments to immigration bills that have attempted to make English the official language, but none have passed. I've read estimates that the US has the fifth largest population of Spanish speakers in the world, and given demographic changes it looks as if that number will only increase. Of course almost everybody in the country can speak English to some degree.
It's not Plovdiv.
Time for a hint or two: It's one of the largest cities in it's country and has had a couple of different names. The first university in it's country was founded there in the fourteenth century. And (tips his hat to delpiero) it contains a World Heritage Site.
