8) What are the entry requirements for Turkey?

You'll need a tourist visa to travel to Turkey. You can apply for a visa online at www.evisa.gov.tr before you go - E-visas can be applied for up to 3 months in advance of your travel date. It costs US$20, payable by VISA or MasterCard debit or credit card only.

If you need assistance applying for your visa, we recommend the Travel Visa Company. That said, other suppliers are also available.

Self service e-Visa kiosks and Wi-Fi areas where visitors can apply for an e-Visa on arrival are no longer available in Turkish airports - you must apply for your e-Visa before you travel.
