In order to visit China and attend ISEC-2023 conference, overseas participants will be required to have valid visas. Obtaining a visa for entry into China is not difficult, but it is important to allow enough lead time for processing your application. Visa requirements vary with time and place, so it's necessary for you to proceed with the visa application based on your own country's situation.

For other issues about Visa applications, please contact isec2023@nju.edu.cn for more details.
