Dear Keith,
That was an April Fool’s “joke post.” There is no Spanish language requirement for residence (of course there is one for citizenship but that has always been the case and most expats live here on residence visas and never pursue citizenship).
Regardless, Keith, we do always encourage potential Panama residents to do their best to learn some Spanish, as knowing at least a little Spanish both helps you show you’re respectful of the locals and can have a very significant positive impact on your Panama experience.
Hope this information helps.
Best regards,
Jessica
