Visitors From Abroad
International Travel Information
OFS 2021 welcomes visitors from around the world. We have compiled a list of resources to help make your travel and show experience as convenient and successful as possible.
Letter of Invitation
A letter of invitation is provided only after you have completed registration for the conference and paid the conference registration fee. Such a letter may be needed to obtain a visa or permission to attend the meeting. If you require an invitation letter please contact the conference organizers via email. The letter will be provided by email. In special circumstances, we may be able to provide a letter prior to registration - please contact Brianna Orr regarding this.
The Conference cannot contact or intervene with any Embassy or Consulate office abroad on your behalf so please begin your visa application process as soon as you determine that you wish to attend OFS 2020. Please provide as much information as possible to avoid delays in receiving your letter. You must register for the conference and pay in full before requesting an invitation letter.
Visa Waiver Program
The Visa Waiver Program (VWP) enables nationals of 36 participating countries to travel to the United States for tourism or business (visitor [B] visa purposes only) for stays of 90 days or less without obtaining a visa. The program was established to eliminate unnecessary barriers to travel, stimulating the tourism industry, and permitting the Department of State to focus consular resources in other areas. VWP eligible travelers may apply for a visa, if they prefer to do so. Nationals of VWP countries must meet eligibility requirements to travel without a visa on VWP, and therefore, some travelers from VWP countries are not eligible to use the program. VWP travelers are required to have a valid authorization through the Electronic System for Travel Authorization (ESTA) prior to travel, are screened at the port of entry into the United States, and are enrolled in the Department of Homeland Security’s US-VISIT program.

- The purpose of their stay in the United States is 90 days or less for tourism or business (Visitor (B) visa) purpose of travel.

VWP travelers who have been admitted under the Visa Waiver Program and who make a short trip to Canada, Mexico or an adjacent island generally can be readmitted to the United States under the VWP for the balance of their original admission period. See the Department of Homeland Security’s Customs and Border Protection (CBP) website for additional details. Also VWP nationals resident in Mexico, Canada or adjacent islands are generally exempted from requirements to show onward travel to other foreign destinations. Learn more at the CBP website.
