For information on applying for a Visa, travel without a Visa, and the Visa waiver program, vist the Visa Application page.
Nonimmigrant visas are for international travelers (citizens of other countries), coming to the U.S. temporarily for a wide variety of reasons, including tourism, business, medical treatment and certain types of temporary work. While in the U.S., temporary visitors are restricted to the activity or reason for which their nonimmigrant visa was issued, with few exceptions. Please allow ample time for visa processing, as the application process can take several months in some countries. Should you need a Letter of Invitation for your Visa application, you may download a welcome letter, not currently available, from the National Academies website.
To obtain a Visa and enter the U.S., you must begin by completing an application form, DS-156. Contact the U.S. Embassy in your country to make an appointment. Take your application, passport, a photograph, and supporting documents to the embassy or consulate, where you will be interviewed about the purpose of your visit. The Consular Officer at your embassy or consulate will decide what kind of visa you need, when you apply. You must also pay an application fee. The visa allows youto travel to a U.S. port-of-entry where an official will again look at your travel documents before granting you permission to enter the country. To determine if you need a Visa, or for more information on the application process, visit the National Academies website.
The leadership of the National Academies is working with the U.S. government to develop better Visa application and processing. If anyone in your group is experiencing difficulties obtaining a Visa, please report the case to the National Academies by completing an online questionnaire.

Arriving in the U.S.
On the airplane, you will be asked to complete a short arrival/departure form. You will need your visa and/or passport handy. You will need to present your visa and/or passport at the port of entry in the United States. Most often that port of entry will be the airport where you land.
When you deplane, follow signs for non-citizen entry. At that location, a Department of Homeland Security official will interview you and verify all of your paperwork. Under the US-VISIT Program of the Department of Homeland Security, most people arriving in the U.S. will submit to a finger scan of the two index fingers and a photograph. Once admitted, you will receive an immigration stamp and proceed to baggage claim and customs. For information about arriving in the U.S., including arriving by land or sea, see US-VISIT.
Upon arrival in the U.S., certain foreign citizens are required to register under Special Registration, which is the National Security Entry Exit Registration System (NSEERS) program. Registration under NSEERS is a distinct process from US-VISIT.
