Visa changes for visitors to US
Under the US Visa Waiver Program (VWP), citizens of participating countries are allowed to visit the US without first applying for visas. Each must first fill out the Electronic System for Travel Authorization (ESTA) form online and receive approval before traveling to the US (whereas, in contrast, a visa must be applied for at a consulate). The ESTA application can be found at https://esta.cbp.dhs.gov/esta.
