Amerikaiak tényleg ki tudják játszani Schengen 90 napos korlátját, hogy korlátlan ideig élhessenek Európában papírok nélkül?

Találtam egy irományt, ami elég érdekesnek tűnik:

"In summary, the diplomatic note of April 4th 1991 (attached), overrides Schengen rules. US Citizens can stay in Poland indefinitely, as long as they leave once every 90 days. Every time you re-enter Poland, the 90 days start again. More importantly, you don't even need to exit the Schengen area. You simply need to go to a neighboring country, like Germany or the Czech Republic, and have some sort of proof that you did.

So why does this mean you can live anywhere in Europe then? Because Schengen rules eliminate internal border control checks. Whenever you fly or take a train to a neighboring country, there are no passport checks. So effectively, once you enter Schengen (via Poland), you can stay in any country you like. When you exit Schengen, make sure to do so via Poland as well."
