Travel Information

Below you can find some useful information regarding travelling to the USA.


A foreign national traveling to the United States to conduct temporary business, such as attending or speaking at a conference, needs a visitor visa (B-1), unless qualifying for entry under the Visa Waiver Program.
Citizens of Canada traveling to the United States generally do not require a nonimmigrant visa, except for the travel purposes described here.

The Visa Waiver Program (VWP) permits most citizens of 38 countries to travel to the United States for business or tourism for stays of up to 90 days without a visa. Travel to the US under the VWP requires Electronic System for Travel Authorization (ESTA) approval.
Upon completion of an ESTA application, a traveler is notified of his or her eligibility to travel to the United States under the VWP. See additional information.

For those visitors who will need to get a visitor visa, visa appointment wait times can vary significantly from country to country.
