Visa Information

Visa Requirements

Conference participants should familiarize themselves with visa requirements well in advance of the conference. The ICAP 2014 organizers encourage you to apply for your visa as early as possible, at least 3 months prior to this conference (by April 2014).

ICAP 2014 CANNOT INTERVENE with U.S. Embassies abroad or the State Department in Washington, DC, on behalf of any participant. If you need a personal letter of invitation to attend the Conference, please indicate so when registering on the registration website. Your letter will be emailed (in pdf format) once the registration has been confirmed. We ask that you please register as early as possible in order to receive it in time.

The U.S. has updated its visa policies to increase security for our citizens and visitors. It will likely take you longer to get a visa than it used to, and you will find that a few new security measures have been put into place. For details that may apply specifically to your country, see information posted by your nearest consulate or embassy.

Passport Requirements

As of October 26, 2006, any passport issued on or after this date by a Visa Waiver Program (VWP) country must be an e-Passport for VWP travelers to be eligible to enter the U.S. without a visa. The most common way of entering the U.S. without a visa is through the VWP. The 27 participating VWP countries can be found online.

Other U.S.-Visit

These notes presume that non-U.S. citizens/residents traveling to the U.S. for attendance at the ICAP 2014 do so for this reason only. The guidance offered may not be appropriate for plans which include visits to other institutions, vacations or other objectives.


Problems encountered in visa applications or in the admission process can be reported to the International Visitors Office by completing the questionnaire on their website. The International Visitors Office can inquire at the Department of State about the status of visa applications that have been pending for more than 20 days. To help the International Visitors Office to identify you as a participant, please be sure to include the name of our meeting (International Conference on Atomic Physics) in the "Purpose of Visit" field on the questionnaire.
