Depending on your citizenship, you may need a visa to travel to the United States to attend ISRI2024 Convention & Exposition.

Individuals requiring a visa must first purchase a convention registration. Once the payment has been processed, confirmation will be returned to the email address included on the registration form. If for any reason, you are unable to secure an appointment for a Visa or Visa approval, you will be refunded 100% of the convention registration fee paid. To receive the refund, you must provide documentation of Visa denial such as a letter from the consulate office.

Letters of invitation for ISRI2024 Convention & Exposition may be requested at the time you register and only after you paid in full. When registering you will have an option to select a Visa letter of invitation. Please be prepared to provide the following information:

  • First and surname as appears on passport
  • Nationality
  • Passport number
  • Passport date of issue
  • Date of birth
  • Gender
