Europe isn’t one country. The rules will be different depending on what country you’d like to visit. So, first you should make a bit of a plan, then… open a Rough Guide or Lonely Planet or contact the relavant embassies or a travel agent.

But to get you on the right track, there are 15 countries that have a common tourism policy. They are called the Schengen countries, (named after the town of Schengen where they signed a treaty.)

They are:

Austria
Belgium
Denmark
Finland
France
Germany
Greece
Iceland
Italy
Luxembourg
Netherlands
Norway
Portugal
Spain
Sweden

OK cool. Here’s another question. My mother is getting remarried in Jan. and is going to fly me back to the states for like a week for the wedding and all. I assume that after that week I can then go back with a fresh start on a new 90 day stretch. Or is there a certain number of days that you have to be back in the US before you can return? Sorry if these are silly questions, but I don’t know anyone personally that I can ask.

It’s 90 days within a 180 day period. Meaning if you stayed in 90 days, went back for the wedding, you would have to be out for 90 days before you could re-enter.

It’s a common mistake regarding that rule, a lot of people think that they can "go to morocco" for one day, and then come back.
