Visas/Temporary Visitors to the U.S./Passports
International visitors add greatly to our nation’s cultural, education and economic life. We continue the proud tradition of welcoming visitors to the United States, with secure borders and open doors.
Most Canadian citizens and many citizens from Visa Waiver Program countries can come to the United States (U.S.) without a visa if they meet certain requirements. All Visa Waiver Program travelers 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 additional digital photograph and e-passport requirements for VWP travelers. Other foreign citizens will need a nonimmigrant visa.
Nonimmigrant visas are for international travelers (citizens of other countries), coming to the U.S. temporarily. The visa, placed in your passport when issued, allows you to travel to a U.S. port-of-entry (airport, for example) and request permission of the Department of Homeland Security (DHS), Customs and Border Protection immigration officer to enter the U.S. 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 nonimmigrant visas available under immigration law, please see our Visa Types for Temporary Visitors webpage. The Consular Officer at the U.S. embassy or consulate will 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:
- Review your visa status, and find out if you need a U.S. visa or a renewal.
- Review the Visa Wait Times information for interview appointments and visa processing at each embassy and consular section worldwide available on our website. 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 other instructions.
- Plan on an interview, as well as quick inkless fingerprint scans at the U.S. embassy or consulate, which is required for most visa applicants. Some visa applications require additional administrative processing, which requires some additional time. Applicants are advised when they apply.

U.S. Visa Policy
We welcome travelers from around the world coming as temporary visitors, or to immigrate to the United States, in accordance with U.S. immigration laws.
Visa Processing Time Information
Recent changes in U.S. laws governing visa policy and procedures have increased the amount of time it can take to obtain a visa. Apply early! Even with the visa processing improvements that have been made and will continue to be made, it is inevitable that delays will sometimes occur. Processing times will vary. The State Department’s goal is visa delivery no more than 30 days from the time of application in most cases, although cases that require administrative processing could take longer. Most administrative processing is resolved within 60 days of application. When administrative processing is required, the timing will vary based on individual circumstances of each case. Therefore, before making inquiries about status of administrative processing, applicants or their representatives will need to wait at least 90 days from the date of interview or submission of supplemental documents, whichever is later. If you want to visit the U.S. and require a visa, plan to schedule your visa interview well in advance of your departure date. Learn more by reviewing this website information and contact the U.S. embassy or consulate where you will apply for detailed “how-to” instructions.
Visa Waiver Program
The Visa Waiver Program (VWP) enables nationals of 37 participating countries* to travel to the United States for tourism or business (visitor [B] visa purposes only) for stays of 90 days or less without obtaining a visa. The program was established to eliminate unnecessary barriers to travel, stimulating the tourism industry, and permitting the Department of State to focus consular resources in other areas. VWP eligible travelers may apply for a visa, if they prefer to do so. Nationals of VWP countries* must meet eligibility requirements to travel without a visa on VWP, and therefore, some travelers from VWP countries* are not eligible to use the program. VWP travelers are required to have a valid authorization through the Electronic System for Travel Authorization (ESTA) prior to travel, are screened at the port of entry into the United States, and are enrolled in the Department of Homeland Security’s US-VISIT program.
