These non-EU/EFTA visa-free visitors may not stay more than 90 days in a 180 day period in the Schengen Area as a whole and, in general, may not work during their stay (although some Schengen countries do allow certain nationalities to work - see below). The counter begins once you enter any country in the Schengen Area and is not reset by leaving a specific Schengen country for another Schengen country, or vice-versa.

Without an entry stamp, you may be treated as an overstayer when you try to leave the Schengen Area; without an exit stamp, you may be denied entry the next time you seek to enter the Schengen Area as you may be deemed to have overstayed on your previous visit. If you cannot obtain a passport stamp, make sure that you retain documents such as boarding passes, transport tickets and ATM slips which may help to convince border inspection staff that you have stayed in the Schengen Area legally.
