Yes, you can enter Turkey using a valid Schengen visa, but for many nationalities (including Indians and Pakistanis), this is a "supporting document" that allows you to apply for a Turkish e-Visa rather than a traditional sticker visa. In 2026, if you hold a valid, unexpired Schengen, US, UK, or Ireland visa (or residence permit), you are eligible to apply online at evisa.gov.tr. The process is fast (often approved within 24 hours) and typically costs between $20 and $60. It is a peer-to-peer essential to ensure your supporting Schengen visa is still valid on the day you enter Turkey. If your Schengen visa is single-entry and has already been used to enter the Schengen zone, it may still be valid for the Turkish e-Visa as long as the "expiry date" hasn't passed. If you do not have one of these qualifying visas, you must apply for a traditional "Sticker Visa" through a Turkish consulate or authorized center (like Gateway International), which takes significantly longer (5–15 days).
