Well my only experience is at LA, since 9/11, and if you are not from a
country assigned Visa Waiver status then you definitely need a Visa for a
stopover on an international flight. This is because there is no stopover
lounge now. Everyone has to clear immigration and collect their suitcases.
The only exception I have had is when my continued flight was on the same
plane and then I did not need to collect suitcases, but still had to go
through immigration. After going through immigration you then go out on the
street, and back in through the scanners.
