International Attendees

We welcome attendees from all over the world. Here’s some information to help you research any visa and travel requirements.

Visa Applications and Passport

If you are traveling to the US from another country, you will need a passport and should check whether you will need to apply for a visa. If so, you should apply as early as possible—at least six months before your intended arrival. If you need a visa, we strongly encourage you to register as soon as possible for the conference to receive your letter of invitation, which is helpful in the visa application.

Citizens of certain countries do not need to apply for a visa to travel to the US. These are known as Visa Waiver Program countries.

All visitors traveling to the US (including from Visa Waiver Program countries) must register their details online at least three days in advance of travel. The Department of Homeland Security (DHS) Electronic System for Travel Authorization (ESTA) is a free, automated system used to determine the eligibility of visitors to travel to the United States. It collects the same information as the paper I-94W form you usually complete when traveling to the United States. ESTA applications may be submitted at any time prior to travel, provided it is three days in advance of travel. An ESTA authorization generally will be valid for up to two years. DHS recommends that travelers submit an ESTA application as soon as they begin travel plans.

If you are NOT eligible to travel under the Visa Waiver Program, please vist the US State Department website for up-to-date information on applying for a US visa, visa categories, wait times, and FAQs etc. 

Visa questions should be directed to the National Academies International Visitors Office: visas@nas.edu.
