As of my last knowledge update in September 2021, the eligibility criteria for applying for an e-Visa to Turkey may have changed, so it's important to check the latest requirements on the official website of the Turkish government or the nearest Turkish embassy/consulate. Typically, e-Visas to Turkey are available for citizens of many countries, including those in Europe, the Americas, Asia, and Oceania. Travelers planning tourism, business, or transit visits are often eligible for e-Visas. The e-Visa allows stays for up to 90 days within a 180-day period. It's crucial to review the specific requirements and application process based on your nationality before planning your trip.
