Do I need an ESTA approval if I'm transiting the United States and route to another country
Visiting another country via United States.
ESTA for transiting the United States.
Qualified nationals or natives of countries that come under the Visa Waiver Program require either travel approval or a visa to travel the United States. On the off chance that a traveller just wants to travel through the United States on route to another country, when he or she finishes the travel approval application in ESTA, the traveller should choose "Yes" for the question "Are your travelling through the US to a final destination in another country?"
