International Attendees

Letters of Invitation

CAMX will provide a letter of invitation to registered attendees and exhibitors. It is recommended that you have this letter for your visa application and interview. Letters of recommendation should be requested at least 3 months prior to the event. To request a letter of invitation, submit a written request to Anessa Sanchez. Within this request, indicate if the letter should be addressed to the requestor or to the embassy/consulate.

Note: Country entry procedures are the responsibility of the individual, not CAMX. CAMX will not intervene with any decisions made by any government on behalf of the attendee nor accept responsibility for a filed entry visa. CAMX is not acting in the role of a sponsor and accepts no responsibility for the individual’s stay in the country.

The following is required when requesting a letter of invitation:

  • Full name as it appears on Passport
  • Passport nationality
  • Passport number and expiration date
  • Personal address/phone/email
  • Address of Embassy, High Commission or Consular Office to which the letter must be addressed
  • Purpose of attending to include whether you are a committee member, exhibitor or presenter
  • Any other unique information required by the embassy (for example, total costs of event, name of in-country sponsor, etc.)
  • Address where the requestor would like this letter sent (email, fax or mailing address)

Letters will be e-mailed as a PDF document to the requestor, unless otherwise requested. If the requestor prefers to receive the letter by mail, allow sufficient time for delivery (2-3 weeks). The costs of any other form of transmission besides email – e.g. by courier or registered post – and subsequent letters of support must be paid for by the requestor. If you choose this option, please include your UPS number with the email request.
