Is a short international layover enough time to clear customs?
International connections with tight windows make it difficult to figure out where customs and immigration take place, especially when switching terminals or rechecking bags. Non-citizens or travelers facing long immigration lines risk missing their connecting flights because standard itineraries do not account for these delays.

“Hi, looking at a flight from Europe that has a layover of 2 hours and 47 minutes at JFK in the afternoon.”source ↗
“I am a not a citizen so immigration takes longer than usual (+ there’s collecting and rechecking bags) but even then I have done international to domestic transfers at SEA and LAX in the past and they have never taken me more than 1.5 hours. Never done this at JFK before so some insight would be appreciated.”source ↗
“Do I need to exit the transfer section and re-enter through security check and passport check as I'm technically getting into a completely different flight or is it enough that I use the transfer section and go through the security check there?”source ↗
“I’m aware that I’m cutting it close, but I’m looking for HOW close….1h45m layover”source ↗
