Whoa you confused me there for a minute. I was about to type about how you most definetly need a visa for the U.S. even if you stay for >90 days, but that's only for countries that don't feel the love... like Brazil
Anyhow, before I gave you the wrong information, I researched and found out that you don't need a visa if you stay in the U.S. for >90 days, but ONLY if you are from a country that is part of the VWP (Visa Waiver Program).
That would be Andorra, Austria, Australia, Belgium, Brunei, Denmark, Finland, France, Germany, Iceland, Ireland, Italy, Japan, Liechtenstein, Luxembourg, Monaco, The Netherlands, New Zealand, Norway, Portugal, San Marino, Singapore, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. So, you'd have to be from one of these countries to apply for the no-visa thing.
(I'm putting this list just incase you aren't from one of these countries. If you aren't, you'll have to obtain a visa before visiting. You're also suppose to expect to be photographed and fingerprinted once you enter.)
Now about the leaving and coming back, I've wondered that too, but I've never gotten a solid answer. I would think that it would depend on the specific country that you're entering twice.
Are you asking this out of curiosity, or ar you going to apply this to whatever country you're going to? Like, do you plan on going to the U.S. for 89 days then going to Canada just to return to the U.S. two days later? Or is this for European countries like you're going to France then Spain and Portugal, to come back to Spain again?
Also, do you plan on using the no-visa thing because you just happen to want to visit a place for over three months or you plan on "residing" there for a while, but don't want to bother with a visa?
It all really depends on the circumstances and the specific countries. If you want, I can check the specific embassies, but I'll need to know under which circumstances you'll need to stay in that country for so long (like if you're planning on going to the U.S. for longer than 90 days, I'd tell you that it'd be easier to get a tourist visa that lasts for ten years where you can stay in the U.S. for up to six months at a time).
If I can't find it on the embassy websites, there are ton of other people here willing to help you out
