Visas should be applied for well in advance of your intended departure date.
Please note that while we wish to assist our participants by providing the visa invitation letter, we do not contact the Embassy or Consulate on behalf of participants, and we are not able to influence Embassy / Consulate procedures or decisions.
Applicants should contact the nearest local US Embassy to determine the appropriate timing and conditions of the visa application.
Invitation Letter
Participants can request an official invitation letter via the online registration. The letter will only be issued to registered participants who have paid their registration fee in full.
The invitation letter aims to assist participants who need to obtain a visa, or permission to attend the conference, and is not an official invitation letter covering fees or any other expenses.
If a participant’s application for a visa is refused, the conference planner will refund the paid registration fees only when a copy of the refusal letter is received before October 20, 2025.
