Procedure to Request an Official Letter for Visa Application
for Conference Delegates and Exhibitors
attendees may need a letter of "invitation" in order to obtain a visa
to visit the United States. We strongly advise to start the visa
application process as early as possible. Kindly note: the event
organizer will not be able to contact or intervene with Embassy or
Consulate offices on your behalf.
conference attendees and exhibitors must be registered and must have
paid the required registration fees* before requesting an official
letter for visa application purposes.
To ensure a successful request for a letter for visa application purposes, please be sure to send the following details:
note that in the absence of the above mentioned information, or if you
are not a conference attendee or exhibitor, we will not be able to
process your request.
- Full name
- Date and place of birth
- Passport number
- Complete mailing address
- Telephone and fax number
- Email address
- Name and contact information of your representative at the Embassy
As part of security procedures, many applications for visas are sent to the U.S. State Department for a security review.
We advise attendees traveling to the United States to apply for a visa
as early as possible (at least three months before the visa is
needed.) Because of the number of visas being processed and the need
to be thorough with the reviews, this can take as long as 8 weeks, especially for those countries that are on the State Sponsors of Terrorism List.
It is the traveler's responsibility to check and confirm current visa requirements to enter the United States. The Conference Organizers cannot be held responsible for travelers that do not confirm their visa requirements or obtain the appropriate paperwork for travel to the conference.
Conference registration fees are refundable (less the designated
administrative fee) if the visa application is denied. The refund
request must be received in writing 14 days before the conference start
date. No refunds will be made for cancellations received after that
This procedure is intended to assist participants who need to obtain a
visa to attend the conference and is not an official invitation
covering fees and/or any other expenses or financial support for
attendance. The organizers can assume no responsibility for the
outcome of your visa application.
