I'm a freelance internet worker, working and traveling at the same time. I have a US Passport.
I wanted to legally spend 9 months in Europe - Czech Republic, Germany, Spain, and/or Budapest. While I'm there, I'll work on my business in the US, rent an apartment, and do tourist stuff.
What's the smartest way to spend 6-9 months like this in Europe? I typically spend 2-3 months in the same place before traveling on. The Schengen 90/180 day rule doesn't seem that complicated, but I don't want to leave for 3 months in the middle.
