COPENHAGEN, DENMARK — What exactly is an expiration date? Much after the fact, I pondered that question following a hassling by a usually-friendly staff of customs-passport inspectors at the airport in Copenhagen, Denmark.
This is our third trip here. Our passports, acquired in June 1999, show proof of our visits to this area twice before, in 2006, 2008 and this year. The policy is for each visitor landing at Kastrup International to furnish proof of residency.
