I haven't entered the US at ORD for about a year now.

Do they have a dedicated GE-exit at the customs meanwhile? How's the situation since the APC are open to ESTA-travellers?

Although I have with 1:45h enough time to make my connection, I'm a bit worried that I'll spend more time at the customs than anywhere else.

Bonus question: I read somewhere in this thread that an incoming international flight disables TSApre on a connecting flight. Is that still the case?
My last BPs always indicated TSApre for the connecting flight (departing from IAD), but lack of TSApre at IAD midfield I could never test it...
