Travel Requirements

Starting in December 2021, all air passengers, regardless of vaccination status, must show a negative COVID-19 test taken no more than one day before travel to the U.S. International visitors will also be required to show proof of vaccination. With specific exceptions, noncitizens who have been in certain countries during the past 14 days may not enter the U.S. Please review the CDC website to stay up to date with the latest information regarding travel requirements and restrictions.

Visa Waiver Program (VWP) Information

The U.S. Visa Waiver Program (VWP) allows citizens and nationals from 38 countries to travel to and enter the U.S. for business or visitor purposes for up to 90 days without obtaining a visa. Please review the U.S. Department of State website to stay up to date with important government announcements.

VWP Requirements

  • As of April 1, 2016, you must have an e-passport to use the VWP. An e-Passport is an enhanced secure passport with an embedded electronic chip. You can readily identify an e-Passport, because it has a unique international symbol on the cover.
  • All eligible travelers who wish to travel under the VWP must apply for authorization using the Electronic System for Travel Authorization (ESTA) website.

ESTA is an automated system used to determine the eligibility of visitors to travel to the U.S. under the VWP. It collects the same information as the paper I-94W form that VWP travelers currently fill out en route to the U.S. ESTA applications may be completed online and submitted at any time prior to travel, though it is recommended that travelers apply when they begin preparing travel plans.

An ESTA authorization generally will be valid for up to two years. Authorizations will be valid for multiple entries into the U.S. DHS recommends that ESTA applications be submitted as soon as an applicant begins making travel plans.

Visa Information

Some participants from outside the U.S. will need to apply for a visa at the American Embassy, Consulate or other visa-issuing office in their country of origin. To obtain a visa you will need a letter of invitation, a valid passport, a photo ID and a completed Form DS 156 (nonimmigrant visa application form).

A visa is not required for visitors from countries participating in the Visa Waiver Program. Currently, 34 countries are enrolled. For more information about visa requirements, how to apply for a visa or the Visa Waiver Program, visit the “Visas for Foreign Citizens” section of the U.S. Department of State website. Use the Visa Wizard as a guide to help foreign citizens understand which visa category might be appropriate for their travel to the U.S.

Italian Attendees

DDW has designated Marben Srl (in collaboration with DDW International Group Housing) to act as delegate by proxy to collect all applications from the Italian Pharmaceutical companies and file them with the local Ministry of Health. Marben Srl will act as the intermediate institution between the Italian companies and the Italian Ministry of Health. For information, please contact Nicole Napolitano at
