International Visitors

International participants of WWETT will find information in this section about the International Buyer's Program, Letters of Invitation, VISA application forms and links to locate your U.S. Embassy or Consulate.

The WWETT Show is proud to be a world class tradeshow and welcomes its international visitors. If you are an international visitor to the WWETT Show, be reminded that the United States government has instituted new, tighter visa requirements for non-immigrant applicants. This may lengthen the amount of time it takes to process your visa application. As a result, get an early jump on your visa application process by obtaining all the necessary documentation.

Whether you are an attendee or exhibitor at the WWETT Show, you must do several things in advance to prepare for your trip. Generally, international travelers need a VISA to enter the U.S. Travelers from certain eligible countries may be able to visit the U.S. without a VISA, through the VISA Waiver Program (VWP).

If you are from a country that does not participate in the VWP, you will need to make an appointment with your U.S. Embassy or Consulate for a VISA interview.

WWETT has a formal International Buyer's Program that provides many benefits for international attendees. Through the U.S. Commercial Service's network of offices in U.S. Embassies and Consulates worldwide, the Trade Event Partnership Program (TEPP) recruits pre-screened foreign buyer delegations and brings them to selected trade shows in the United States, connecting U.S. companies with international buyers. Traveling to the show as participant in the International Buyer's Program allows you to take advantage of the following benefits:

• Pre-arranged and facilitated briefings and meetings with U.S. exhibitors, customized according to your buying
interests. Meetings are organized in collaboration with the delegation leaders.
• Export counseling provided by Department of Commerce staff.
• Matchmaking services between U.S. exhibitors and non-U.S. buyers to discuss exporting or joint ventures.
• Complimentary ticket to the International Reception in appreciation to all international visitors
attending the show.
• Interpreters available for conducting business meetings during the show.
• List of exhibitors who export or indicate an interest in exporting to the group’s country/region of the world.
