If you need a visa to enter Turkey, it can usually be obtained online. Check if this applies to you, and apply in advance, at www.evisa.gov.tr. Do not rely upon any other website as the rules may change suddenly.. Also some websites charge extra for no additional service. In general EU Schengen and UK passport holders don’t need a visa to enter (as of February 2022), for up to 90 days in a 180 day period. North American need a visa costing US$35-50 valid for 90 days, residents of China pay US$ 60 for 30 days, and visa duration and price varies for other nations. Some travelers are not eligible for an evisa and must apply for a conventional visa via their local Turkish Embassy. However these same travelers who are otherwise ineligible with solely their citizenship may be eligible for an eVisa if they hold a valid visa or residence permit for Schengen, USA, UK or Ireland.
