Visa Information

All international attendees who will need to obtain a visa to enter the United States are encouraged to contact the nearest U.S. Embassy or Consulate and begin the application process as soon as possible. Due to the number of visas being processed and the need to be detailed with the reviews, the process can take as long as 8 weeks. Attendees from these countries should start the application process at least 6 months in advance of the meeting. Click here for information on Travel Grants.

Japan VISA

Please look at the list of the countries that have the visa exemption agreement with Japan. If your country is included in the list, you will not be required for a visa when entering Japan under normal circumstances.

If your country is not included in the list, you need to obtain a short-term stay visa (“tanki-shouyou visa” in Japanese) from the embassy of Japan in your country.

Read the Japanese visa guide provided by the ministry of foreign affairs carefully. Please be informed that it is the embassy of Japan in your country that makes a decision on issuing a visa. Usually the procedure takes considerably long, so you need to begin the procedure as early as possible.

VISA Waiver Information

International attendees who are nationals of countries listed in the Visa Waiver Program (VWP) may be able to travel to the United States for 90 days or less without obtaining a visa.
