Most Canadian citizens and many citizens from Visa Waiver Program countries can come to the U.S. without a visa if they meet certain requirements. Visa waiver travelers from ALL 27 Visa Waiver Program countries must present a machine-readable passport at the U.S. port of entry to enter the U.S. without a visa, otherwise a U.S. visa is required. See important information about the 10/26/05 digital photograph and 10/26/06 e-passport requirements for VWP travelers (Learn more) Other foreign citizens will need a non-immigrant visa.

Non-immigrant visas are for international travelers (citizens of other countries) coming to the U.S. temporarily. This visa allows you to travel to a U.S. port-of-entry (airport, for example) and request permission of the Department of Homeland Security immigration inspector to enter the U.S. Please note: a visa does not guarantee entry into the U.S.

International travelers come to the U.S. for a wide variety of reasons, including tourism, business, medical treatment, and certain types of temporary work. The type of visa needed is defined by immigration law, and relates to the principal purpose of your travel. For an overview of the types of non-immigrant visas available under immigration law, please see Nonimmigrant Visa Classifications. Most attendees will be using the B-1 Visa for temporary visitor for business. Please check with the Consular Officer at your embassy or consulate to help you decide what kind of visa you need, when you apply.

Advance planning can smooth the visa application process for you. Apply for your Visa well in advance of your travel!

Important steps to remember:

1. Review your visa status, and find out if you need a U.S. visa or a renewal.
2. Review the visa wait times information for interview appointments and visa processing at each embassy and consular section worldwide available on our website at Visa Wait Times. Visit the embassy or consular section website where you will apply for your visa to find out how to schedule an interview appointment, pay fees and any other instructions.
3. Plan on an interview at the embassy or consulate, which is required for most visa applicants. As part of the visa interview, quick inkless fingerprint scans should be expected. Some visa applications require additional administrative processing, which requires some additional time. Applicants are advised when they apply.
