International Travel to the United States

Although the PAS/ASPR can not grant passports, we provide details and important links about the Visa Waiver Program, Travel Approval Requirements for Visa Waiver Countries, Tips on Successful Visa Applications, and other useful international visa and travel information to help you on your journey. 

Invitation Letter

For a personalized International Invitation letter click this link. Once you complete the form and click submit, a letter will appear with the information you submitted.  You can print this letter as you need.  If you make a mistake, press the back button, correct any information, and resubmit.  If you must apply for a temporary non-immigrant visa to attend a live CME event, you are advised to apply as soon as travel to the United States is contemplated and not later than 3-4 months in advance. APPLY EARLY! The PAS/ASPR offers an official letter of invitation for attendees. The visa letter of invitation though not required for the visa application can assist as a supporting document. Present this letter of invitation from the PAS/ASPR to the consular officer during the visa interview. This letter does not guarantee admittance into the U.S., but can provide compelling evidence for immigration officials to consider. Please note that the PAS/ASPR cannot intervene with either U.S. embassies abroad or with the U.S. State Department on behalf of any participant.

Visa Waiver Program

The Visa Waiver Program (VWP) enables nationals of certain countries to travel to the United States for tourism or business for stays of 90 days or less without obtaining a visa. For more information go to: http://travel.state.gov/visa/temp/without/without_1990.html and click Visa Waiver Program. Travel Approval Required for Visa Waiver Countries Visa Waiver Program (VWP) countries are now required to obtain approval through the Electronic System for Travel Authorization (ESTA) prior to traveling to the United States. This requirement applies to all eligible citizens or nationals traveling under the VWP, ESTA is a web-based system, initially launched in August 2008, which determines the preliminary eligibility of visitors to travel under the VWP prior to boarding a carrier to the United States. It collects the same information as the paper I-94W form that VWP travelers currently fill out en route to the United States. To date, more than 1.2 million ESTA applications have been received, and more that 99.6 percent of applications have been approved, most within seconds. Travelers without an approved ESTA are advised, however, that they may be denied boarding, experience delayed processing, or be denied admission at a U.S. port of entry. Visitors may apply for travel authorization via the ESTA website at https://esta.cbp.dhs.gov

Tips for Successful Visa Applications

• Include a letter of invitation from the meeting organizer.

• When possible, provide proof of professional scientific, and/or education status, society membership and/or meeting registration.

• Visa applications are expected to provide evidence that they intend to return to their country of residence.  Therefore, applications should provide proof of binding or sufficient ties to their home country or permanent residence abroad.  Visa applications are more likely to be successful if done in the visitor’s home country.

• Applicants should present their entire trip itinerary, including travel to any countries other than the United States, at the time of their visa application.

• All applicants must be able to qualify for a visa on their own merits under the requirements of the Immigration and Nationality Act.
