If you’ve visited Istanbul or any of the country of Turkey in the past, you had to stand in line to buy a tourist visa sticker (in cash only, payable in USD or Euro) before getting in a longer line to get through border control and out of the airport. If you forgot to buy the Turkish visa first, you’d have to get out of line and hope that a nice person would let you cut back in once you got the sticker. Now, you can apply online and sail right through to the Immigration line, eliminating one step.
The new e-Visa program is available to citizens of most countries, including the United States, Canada, and European Union. Like the sticker system, it costs $20 and your visa is valid for multiple entries for 90 days (the visa is valid for 180 days but you can only stay up to 90 without applying for residency). You can apply up to 24 hours before departure, though they advise one week. If you forget to apply online, don’t worry, the old visa desk will still be available at the airport.
