***ESTA – Electronic System for Travel Authorization***
Are you visiting the United States from a Visa Waiver Program (VWP) country and currently do not possess a visitor's visa? If so, you will need to complete an official ESTA application by clicking here. You can apply for this for just yourself, or a group of travelers. (To figure out if you are from a VWP county, click here.) In order to complete the application, you will need a valid passport from a VWP country, a valid credit card or PayPal to pay the application fee of $21. See website for more information and requirements.
The application generally takes about 15-20 minutes to fill out and you can check the status of the application by visiting the same site you applied at. Please complete the application at least 2 weeks-72 hours before your scheduled arrival date into the United States. ESTAs are normally valid for 2 years unless you receive a new passport or other important information changes.
