Do British Citizens need a visa for Turkey?
British nationals need a visa to travel to Turkey, except for cruise ship passengers with ‘British Citizen’ passports who arrive at sea ports for tourist visits to the port city or nearby cities, provided that the visit doesn’t exceed 72 hours.
If you’re visiting Turkey as a tourist or on business, you can apply for an e-Visa online before you travel. If you don’t have an e-Visa you can still get a visa on arrival for £20 in cash, although the visa on arrival service is due to be phased out. Getting an e-Visa from the official website before you travel will avoid possible problems or delays at the Turkish border, or when boarding your flight in the UK. See Entry requirements
Do I need to disclose my criminal record when I apply for e-Visa?
A disclosure of criminal record is not required when you apply for e-visa. The information required are; your full name, date and place of birth, passport number and dates of travel.
