An important amendment to the Entry Requirements to Turkey for foreign passport holders – a blank page in passport required for visa stamp. Until December 31st this will be flexible and if a foreign passport does not have a blank page you will be issued a one-off “Entry-Exit form” with your entry-exit stamp on there. You should carry this form with you in Turkey and present it to the border officers, when you leave Turkey. However after the 31st of December the entry will be refused if a passport does not have a blank page for a visa.
