What Is A Letter Of Invitation?

For security reasons, most organizers of international conferences worldwide (not just in the United States of America) resort to first issuing a conference visa invitation letter to their registrants before they can proceed to apply for permission (in the form of visas to travel to their countries. 

By obtaining an Official Conference Invitation Letter, a registrant can demonstrate sufficient intent to travel to a country. This proof is required by the officers at the embassies of the country who are in charge of validating travelers and issuing them travel visas based on their authentic display of “Intent For Travel”.

Conference organizers typically have the following policies in place – 

  • Invitation letters are only sent to confirmed registrants. Registrants are those who have paid the registration fee for the full conference.
  • After receiving their official registration confirmation, registrants must request an invitation letter by either filling in an online application form or emailing a request letter to the organizers. 
  • In order to expedite the preparation of an invitation letter, registrants must provide all the documentation/information required by the organizers.

Obtaining an invitation letter from an organizer doesn’t necessarily guarantee that one’s U.S. visa application will be approved. The letter is simply additional information that explains the visa applicant’s intended purpose of traveling to the United States. Conference organizers do not have any say in the visa issuance process. 

What Are The Requirments For Obtaining An Invitation Letter For A Conference Visa For The U.S.A?

  1. The full name must appear on the application form exactly as it appears on the passport. This is because any discrepancies between the name on the invitation letter and the passport could result in delay and/or denial of the USA conference visa.
  2. If the registrant plans to present a paper, he/she must make sure to include the title of their abstract submission. They don’t have to wait until their paper has been accepted to request an invitation letter.

  4. Each person requesting an invitation letter must complete a separate form. All invitation letters will be issued in PDF format and sent to the registered email addresses of registrants. If a hard copy of the invitation letter is necessitated, registrants indicate this in their applications.
  5. The organizing committee of the U.S. conference reserves the right to request additional information regarding the participant’s affiliation in order to ensure the authenticity of the requests.
  6. Registrants must seek to apply for their travel visas as early as possible in order to avoid the possibility of cancellation.
