Visa Information

DISCLAIMER: The information and suggestions provided below by the AAMAS local organizing committee should be treated as guidelines and not as official information on U.S. immigration policies. 

If you plan to attend AAMAS25, you are strongly advised to exercise due diligence to determine as early as possible whether you need a visa to travel to the USA. If you do need a visa, it will typically be in the visitor visa (B) category (B1/B2, more specifically). If you are a citizen of a country that participates in the U.S. Visa Waiver Program, you should obtain an online travel authorization through the ESTA system before your trip to the USA.

You can find useful resources, especially for information on the Visa Waiver Program, visa categories, embassies and consulates, and typical waiting times, on this page. You are responsible for applying for your visa/travel authorization and obtaining it in time for your visit. The visa application process may vary depending on location and can be lengthy and uncertain, so we earnestly encourage you to start well in advance. 

The AAMAS organizing committee cannot directly participate in the visa application process or provide financial assistance for this purpose. We can produce upon request an invitation letter for you to include in your visa application package.

To obtain your invitation letter, please register for AAMAS25 (visit the registration page) and request an invitation letter by selecting ‘Yes’ on the drop-down menu in response to the non-optional question ‘Are you requesting an invitation letter?’ on the first page of the registration process. After you successfully complete your registration, you will receive a confirmation email that includes, among other things, a link for downloading your personalized invitation letter if you requested one. This letter will include a confirmation of your registration in addition to your name, email address, and affiliation. Please check your spam folder if you do not receive the confirmation email soon after registering.

Please understand that the AAMAS organizing committee does not take any responsibility for the outcome of a visa application accompanied by an invitation letter we provide, and this discretion lies solely with U.S. immigration authorities; of course, if and when contacted by authorities, we will be happy to attest to the validity of an invitation we issued.
