Do you need an onward ticket for the United States?
Required
The strongest statutory case in the dataset — but it applies to the Visa Waiver Program, not to B-1/B-2 visa holders, and not at a land border.
An official page or statute states this condition. The wording is quoted below and the source is linked.

“The alien is in possession of a round-trip transportation ticket…”
The answer depends on how you enter
Visa Waiver Program / ESTA, arriving by air or sea
Required
Round-trip transportation ticket required by statute; the regulation defines the term broadly.
Visa Waiver Program, arriving at a land border
Not required
8 CFR 217.2(c)(2) states in terms that a round-trip transportation ticket is not required.
B-1 / B-2 visitor visa
Not required
No ticket condition exists. The test is intent to depart under INA 214(b); a ticket is evidence, not a requirement.
What the rule actually says
For travellers entering under the Visa Waiver Program, the round-trip ticket is written into statute. 8 CFR 217.2(a) then defines "round trip ticket" broadly: a return transportation ticket on a participating carrier valid for at least one year, an electronic ticket record, airline employee passes, individual or group vouchers, or military travel orders.
Two carve-outs matter more than the rule. First, 8 CFR 217.2(c)(2) is explicit that a VWP applicant arriving at a land border shows financial solvency and a domicile abroad, and that "A round-trip transportation ticket is not required." Second, 8 CFR 217.2 is Visa Waiver Program law and has no B-visa analogue.
For a B-1/B-2 visitor visa the test is INA 101(a)(15)(B) together with 214(b): a residence abroad that the applicant has no intention of abandoning. A return ticket can be evidence of that intent; it is never a condition. Generalising the VWP rule to visa holders is the single most common error in competitor content on this topic.
One more nuance worth knowing: ESTA itself never asks for an itinerary. The requirement bites at the carrier and at the port of entry, not at the point where ESTA is issued.
Who checks
The statutory condition sits on the traveller, and carriers participating in the Visa Waiver Program have their own obligations. What a given airline checks at check-in is not published by any US government page.
A note on airline enforcement, because almost every page on this subject states it as fact: airlines screen these rules through IATA Timatic, a paid business product with no public interface. Nobody outside the industry can check what it says for a given route on a given day. New Zealand is the only authority in this set whose own published text names the check-in desk.
What would make this wrong
- travel.state.gov blocked every automated retrieval attempt (HTTP 403), so the State Department's own wording for the B-visa position was not obtained directly. The statutory and regulatory citations above were.
