For the most up-to-date information regarding US entry and visa policy, please refer to the following resources provided by the US government as you make your travel arrangements and prior to embarking on a trip to the USA.
The Visa Waiver Program (VWP) allows citizens of participating countries to travel to the United States without a visa for stays of 90 days or less, when they meet all requirements. Travelers must be eligible to use the VWP and have a valid Electronic System for Travel Authorization (ESTA) approval prior to travel.
ESTA is an automated system that determines the eligibility of visitors to travel to the US under the Visa Waiver Program (VWP). Authorization via ESTA does not determine whether a traveler is admissible to the United States. US Customs and Border Protection officers determine admissibility upon travelers’ arrival. The ESTA application collects biographic information and answers to VWP eligibility questions. ESTA applications may be submitted at any time prior to travel, though it is recommended that travellers apply as soon as they begin preparing travel plans or prior to purchasing airline tickets.
If you are not a citizen of a participating VWP country, you must apply for a visa. There are several steps to apply for a visa. The order of these steps and how you complete them may vary at the US embassy or consulate where you apply. Details about obtaining a visa and visa application forms can be found here.
