US citizens who plan to visit Turkey for tourism or business purposes must obtain a Turkish visa before arrival. The visa application process can be done online through the Turkish government’s electronic visa application system, or by visiting a Turkish embassy or consulate in the US. The online visa application process is relatively simple and can be completed in just a few steps. The visa fee can be paid online using a credit or debit card, and the visa is typically issued within a few minutes to a few hours. The Turkish visa is valid for multiple entries and allows for a stay of up to 90 days within a 180-day period.
