Next month I'll be going to Miami, FL! From there (or actualy, Ft. Lauderdale), i'll be flying to Cancun, Mexico to meet up with friends.
I'll be flying home (Amsterdam) back through Miami, so i'll exit and enter the US before leaving for home again:
Do I need to fill in 2 separate ESTA applications (Amsterdam - Miami - Cancun AND Cancun - Miami - Amsterdam) or can I leave and enter the country on one application?
Thank you in advance for your help!
