I (EU citizen) will be entering Schengen area with my spouse (US citizen). I understand that we can go through the EU passport lane and that he is not subject to the 90 day rule. We plan on traveling through many Schengen countries but not spending more than 30 days in any single country.
When going through border control, will his passport be stamped on arrival?
I am worried that if he has an entry stamp, it will look like he overstayed when we exit Schengen 6 months later.
