If your journey includes a stopover in Turkey, you might need this specific transit permit depending on your nationality and final destination. The key restriction is that this visa only lets you stay inside the airport transit area and does not allow entry into Turkey or travel outside the terminal. You can only apply if your final destination is Colombia, Mexico, Panama, or Venezuela. The application requires a clear scan of your passport bio page and your onward flight booking details. I found the Turkey Airport Transit eVisa guide really clear about processing times. Standard takes a day or two, but you can choose super rush and get approval within one hour if your connection is tight. The visa is valid for 24 hours from issuance, so apply close to your travel date. While waiting, you can enjoy airport lounges, duty free shopping, or grab a meal at one of the many restaurants. Just remember to carry your printed visa and flight details when you travel.
