WELCOME TO OFFICIAL WEBSITE OF IPBES2
"All participants to IPBES-2 are responsible for obtaining their own visa to travel to Turkey. Visa applications for many nationalities can be made online through the E-visa system. Please refer to the FAQ page to check if you are eligible for an e-visa. Many nationalities, especially in Africa, in addition to e-visa also require a valid Schengan visa to enter Turkey. Please check online or with your nearest Turkish Embassy on your individual requirements."
