Coming to Kosovo...

Greetings!  I am a retired American, (author, editor and former English instructor) wishing to live long-term in Kosovo, and I am finding it surprisingly difficult to even find a webpage which clearly sites regulations for obtaining different kinds of residency visas in Kosovo.  The one site I found was in Albanian with a button to click for English, which, sadly, didn't work.  Can anyone help me out?

Also, If anyone has any tips about how Americans can stay long-term in Kosovo without a work visa, I would be most grateful!

It's so worrying that others have asked about visas for retirement and nobody at all has replied!
