Requesting a Letter of Invitation from ENKWSA for Your Visa Application

Important Facts:

  1. Only Letter of Invitation requests submitted online will be processed. 
  2. A Letter of Invitation covers one individual only. If additional show participants from a company require Letters of Invitation, separate requests must be submitted online.
  3. The show participant must complete online registration for ENKWSA before a Letter of Invitation request can be submitted.
  4. Only Letter of Invitation requests meeting ENKWSA's eligibility requirements will be processed.
  5. Obtaining a Letter of Invitation for ENKWSA does not necessarily guarantee approval of a Visa.  The letter is merely supplementary information that helps explain a Visa applicant's personal situation in determining eligibility.  

Approved registrants will receive a confirmation letter with a link that allows the registrant to request a letter of invitation.

You must include:

    • Participant's e-mail address

    • Participant's date of birth

    • Participant's job title

    • Participant's passport number and/or ID Number

    • City of U.S. Consulate for participant's interview

Delivery Methods:

  1. E-Mail Only (no charge). Your Letter of Invitation will automatically be generated on your computer screen, and you may print the letter from your computer.  This letter is accepted as an original by most local U.S. Embassy personnel for the Visa application.
  2. E-Mail + Hard Copy via FedEx Delivery ($100 fee). Individuals who require an official hard copy of the Letter of Invitation may request to have the Letter of Invitation sent via FedEx. If Letters of Invitation for more than one participant are sent in the same package, only one delivery fee will be charged. E-Mail [email protected] for instructions before you submit your request for Letters of Invitation. Please allow (5) business days for delivery.


The last day a hard copy of an approved Letter of Invitation will be sent via FedEx is January 23, 2012.

From January 24 - January 29, 2012, approved online requests for Letters of Invitation will be sent via e-mail only.

ENKWSA's Visa/Letter of Invitation Web sites will close on January 30, 2012.

International Media
Members of the foreign press, radio, film or other information media must have a Media (I) Visa. Visit the U.S. Department of State Web site here for more information.  

Visa Interviews
A personal appearance interview is required as a standard part of this process. This can increase the processing time. It is expected fewer waivers will be granted for the interview portion of the process. WSA cannot assist you with the interview process, nor can anyone representing WSA call the embassy or consulate on your behalf to provide support for granting a Visa. If you are denied a visitor Visa, you may reapply if there is new evidence to overcome the basis for the refusal. In the absence of new evidence, consular officers are not required to re-examine such cases.

The Visa Waiver Program (VWP) enables citizens of certain countries to travel to the United States for tourism or business for 90 days or less without obtaining a Visa. Not all countries participate in the VWP. Visit the U.S. Department of State Web site here for VWP requirements and a complete list of participating countries.

Members of the foreign press, radio, film or other information media must have a Media (I) Visa and cannot travel to the U.S. using the Visa Waiver Program. Visit the U.S. Department of State Web site here for more information.
