In a nutshell, a friend of mine moved to Spain last month. She's renting a villa.
I recently found out she has a 90-day visa sticker/stamp in her passport, not a resident visa. I asked her what she's doing and she got very frosty with me, saying the process is to get the proper visa once you're there.
AIBU to think that's not how it works and she knows it? I've read you can go to prison for overstaying, I'm worried.
