USA: Onward Ticket & Return Flight Requirements

Do you need a return ticket for the USA?
Yes, if you travel under the Visa Waiver Program. When entering the United States by air or sea under the VWP with ESTA, you must travel on a participating carrier and hold a valid return or onward ticket dated within 90 days of arrival. It is a documented condition of the program.
The ticket cannot end in Canada, Mexico or the Caribbean
A rule that catches many travelers out: under the VWP, your return or onward ticket must not terminate in Canada, Mexico or an adjacent Caribbean island — it has to show travel onward to another country. The exception is travelers who reside in Canada, Mexico or those islands, who are generally exempt from this part of the rule.
Land borders work differently
If you enter the US by land from Canada or Mexico, the round-trip-ticket and signatory-carrier requirements do not apply in the same way. The strict onward-ticket rule above is specifically for air and sea arrivals under the Visa Waiver Program. If travelling on an e-ticket, carry a printed itinerary for the inspector.
