Explore resources on visas and passports for those traveling internationally at AIA24, including information on the U.S. Visa Waiver Program.

International travel to AIA24

Individuals travel from all over the world to attend the AIA Conference on Architecture & Design 2024. Generally, international travelers need a visa to enter the United States. However, the Visa Waiver Program (VWP) enables citizens or nationals of participating countries to travel to the U.S. for tourism or business for stays of 90 days or less without obtaining a visa. You must have a valid passport to qualify for the VWP.

For additional information on obtaining a U.S. visa, applying to the VWP, and more, please explore the following U.S. visa resources.

Letter of invitation

When applying for a visa, you will need to provide an official letter of invitation. Your U.S. Embassy or Consulate will use this letter as one piece of information to determine your eligibility for a visa.

During online registration for AIA24, you will be asked if you need a letter of invitation or visa letter. By checking yes, you will be prompted to enter some profile information. Once you have completed the registration process, a copy of the letter—saved in a protected PDF—will be sent via email to the address you provided during registration.

Please print this letter and attach a copy of your AIA24 registration confirmation to use as supporting documentation in your visa interview. Because the timeframes for visa processing are difficult to predict, plan to apply for your visa at least two months before your scheduled trip to avoid delays in processing. Your U.S. Embassy or Consulate can answer questions about specific visa requirements and wait times.

NOTE: The AIA Conference on Architecture & Design has no influence over the issue of a visa. We are not able to contact U.S. Embassies or Consulates in support or on behalf of individuals attempting to gain entry into the U.S. to attend the AIA Conference on Architecture & Design. Please direct specific questions to your embassy.
