Invitation Letter

Conference participants may need a Thai visa to enter Thailand. To avoid uncertainty, participants will be advised to apply for a visa as early as possible. It is recommended that they apply for a Thai visa at least 1 month in advance.

For most attendees, it is easier to apply for a Tourist ("L") visa; an invitation letter is NOT required for obtaining a Tourist visa.

If some participants need another type of visa that does require an invitation letter, the ICMSS 2025 local arrangement committees will be glad to help. To obtain an invitation letter, please send e-mail to icmss_icmss@163.com, together with your registration info., and in the case of being an author, your accepted paper ID. The conference secretary will then send a formal invitation letter issued by the organizing committees by email. Please note that the letter may be helpful for your visa application, but cannot guarantee you a visa.
