international attendee requirements

 As a general planning guideline for attendees from outside the United States requiring entry visas, due to the scientific nature of the IEST meeting, the US State Department recommends that any required visa applications should be made no later than 90 days in advance of the travel. Please be aware that your registration information and correspondence may be forwarded to US authorities. Whenever possible, IEST conferences are registered with the US State Department.

  • All International Attendees must be pre-registered prior to IEST granting invitation letter requests.
  • Complete the request form below to request an invitation letter.
  • All invitation letters are generic in nature and will be sent as a secure PDF that can be printed out by the requester. No print copies will be mailed. 
  • IEST is not responsible for missing, lost, or undelivered invitation letters.
  • For individuals registered 90 days prior to the start of the conference, who fail to obtain a Visa, IEST will refund the registration amount less a $75 processing fee.
  • Individuals registering after 90 days prior to the start of the conference, who fail to obtain a Visa, will be refunded based on the regular cancellation policy.
