International Visa Information:

We advise anyone who may need a visa to apply early. Visa applicants should apply at least 3 months in advance of the meeting. Security-related policies have greatly increased the processing time for visa applications. U.S. consular officers now usually interview applicants as part of the application process.

If you need a letter of invitation, e-mail Synchrotron Environmental Science IV to make your request.
