So I don't know why but for some reason even if you're only changing flights in the US you need a full transit visa(if you're from a country that's not part of the visa waiver programme obvs). Was a big pain when travelling to Costa Rica from Europe, because 90% of flights there change in US, which means having to book a visit at the Embassy, pay $150 and pray the consul actually gives you a visa so you can spend 2 hours on US soil to change flights. In comparison when changing flights in Amsterdam you don't need a Schengen visa, the airport is designed to accommodate people changing flights without leaving the airport.
