If you need a visa, be sure to apply early. We recommend applying three to four months before your date of travel to allow sufficient time to process your application.

Travelers entering the United States under the Visa Waiver Program need a valid ESTA approval. The Electronic System for Travel Authorization (ESTA) is a free, automated system used to determine the eligibility of visitors to travel to the United States under the VWP.  Learn more about the Visa Waiver Program and ESTA
