Zman: Otherwise, on a US passport you will need to exit PL before your 90 days expire. To get a stamp in a passport, all you have to do is leave Schengen zone for at least one day or so. For example to Ukraine.
Wrong. The presence of a stamp does not confer any residency rights - under Schengen law, the stamp is solely for informational purposes for the traveller. The deal is any 90 days in an 180 period regardless of what stamps are in the passport (or indeed, if any stamps are present at all).
For what it's worth, it depends when his mother obtained American citizenship as to his entitlement to Polish citizenship.
