Law /
Visa Stamp if you overstay (American with a Polish Wife) [29]
I realize this is a very old thread, but my research conflicts with the consensus here that Americans cannot 'reset' their 90 days per 180 days limit in Schengen by going to Germany or Ukraine for a day and coming back. In 1991 the US and Poland created a bilateral agreement that allows this (see below). There is a lot of conflicting information and opinions here about this topic and I would like to finally get a clear answer from someone who knows more about it.
At washington.mfa.gov.pl/en/waszyngton_us_a_en_consular_information_2/waszyngton_us_a_en_visas it says "IMPORTANT FOR THE US CITIZENS: Based on an exchange of diplomatic notes between Poland and the USA, since April 15th, 1991 the US citizens are allowed to enter Poland for
any 90 days period without visa. The common rule 90 days of stay in 180-day period does not apply in this case."
The above mentioned diplomatic note is attached as a PDF.
Other posts on this forum have even mentioned that both the US embassy in Poland, and the foreigners' office(s) have told Americans in Poland that they may simply leave for a day to reset their 90 day limit, and they just have to have a hotel receipt or passport stamp to prove it. If this is in fact true, it is very helpful for Americans wishing to stay in Poland more than 180 days per year, and for Americans already here who are getting close to overstaying.
There are also posts from those who have said that they unsuccessfully attempted to get a fresh 90 day limit by going to another country for a day and coming back to Poland based on their knowledge of this US-Poland agreement, and were then banned for a year. My guess is that the bilateral agreement is still in effect, but that many border guards simply do not know about it. Does anyone here have firsthand experience with this? Perhaps anyone trying to reset their 90 day limit wit this method should print out the diplomatic note and keep it on them while crossing the border in case they face difficulty with a boarder guard.
Is it true? Can Americans in Poland really reset their 90 day limit whenever they want by going to Lviv or Berlin for a day?
