Obtaining a Visa
If it is necessary for you to obtain a visa to attend this conference, you can find relevant information about the application process by visiting Travel.State.Gov and reading about Business Visitor Visas.  Apply for your Visa several months in advance of your travel.

Important steps to remember:

  • Review your visa status, and find out if you need a U.S. visa or a renewal.
  • Review the visa wait times information for interview appointments and visa processing at each embassy and consular section worldwide available on the U.S. Department of State website at Visa Wait Times.
  • Visit the embassy or consular section website where you will apply for your visa to find out how to schedule an interview appointment, pay fees and any other instructions.
  • Plan on an interview at the embassy or consulate, which is required for most visa applicants. As part of the visa interview, quick inkless fingerprint scans should be expected. Some visa applications require additional administrative processing, which requires some additional time. Applicants are advised when they apply.
