Check Your Passport Before Booking Travel
If your passport is expired or due to expire soon, please be sure to renew it before your trip. Visitors to the United States are typically required to be in possession of passports that are valid for six months beyond the period of their intended stay.
If you need an entry visa, please visit your nearest U.S. Embassy or Consulate to obtain the necessary documents — and please plan in advance to allow enough time for the visa to be processed. Visit the U.S. Department of State website for information on the visa application process.
The following information is for initial reference only. Please visit the US Department of State website and other official U.S. government websites (listed below) for the most current and accurate information for planning your travel to the United States.
Visa Waiver Program (VWP)
Most citizens or nationals of the countries participating in the Visa Waiver Program (VWP) are permitted to travel to the United States for business or tourism for stays of up to 90 days without a visa. Please check the relevant requirements with the U.S. State Department or the U.S. Department of Homeland Security.
In order to travel without a visa on the VWP, you must have authorization through the Electronic System for Travel Authorization (ESTA). U.S. Customs and Border Protection (CBP) strongly recommends that you check your ESTA status prior to making any travel reservations or traveling to the United States.
Exceptions To Visa Waiver Program (VWP)
Some citizens of VWP countries must apply for a visa to enter the United States using the regular appointment process at a U.S. Embassy or Consulate. This requirement falls under the Visa Waiver Program (VWP) Improvement and Terrorist Travel Prevention Act of 2015 and pertains to:
- Nationals of VWP countries who have traveled to or been present in the Democratic People's Republic of Korea, Iran, Iraq, Libya, Somalia, Sudan, Syria, or Yemen on or after March 1, 2011.
- Nationals of VWP countries who are also nationals of the Democratic People's Republic of Korea, Iran, Iraq, Sudan, or Syria.
Learn more about these exceptions to the VWP and find out how to apply for a U.S. visa.
