However, there are a few rules I have come across as a solo backpacker that just plain piss me off. I have found many threads on the internet showing that many people are also concerned about some of these laws as travelers.
Being an American citizen, I am rather lucky because I get a free waiver visa throughout basically any country in Europe. I also have the right to stay legally as a tourist for 90 days (3 months) in any country in Europe. Unless, you happen to be some countries named Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, and Switzerland. Then you only have 90 days in all of these countries combined.
Looking on how to stay legally in Europe? I had advice on that too! Read more.
Anyway, the truth of the matter is you could be anywhere in Europe. You could have traveled by car and no one stamped your passport. It is actually hard to track your journey through Europe.
You need to calculate it. In fact, I have a calculator right here you can use for free. Check it out!
Chill and take a deep breath. If you have overstayed by one day or 8 months, the fine could still be the same depending on the officer. However, it will not go past 1200 euro. There are many people who are living in Schengen zone countries without residence visas. I would research at your own will for those situations. You can search on bootsnall.com. Working illegally, however, is another issue.
