Well 11 weeks to go ...so the wife asks me how long to clear immigration and customs at O'Hare? She wants to know as we are picking up a hire car and she's fretting about the overnight hotel for our drive. We are in UC on VS39 arriving 130pm. She wants to be on the road for 230!!!!
Sorry to be bearer of bad news .... but ...
Arriving 1:30 and on road for 2:30 ! Not a chance !
That perhaps a little harsh as there is a chance..... but then again a chance of winning the Jackpot on the lottery so you never know !
I have done this route and my son does also regularly...... In our experience, Immigration at O'Hare is something that demands patience for non US Visitors. It can be slow at best with queues on arrival meaning you are a long way from the officers. It does not move quick and can be painful especially when trying to catch onward flights.
Once through Immigration, Customs not normally an issue.
You will then however have to go outside and wait for the Car Hire Bus to come around to the correct stop and take you off to their lot. Depending how many on the bus and how quick you get to the desk another variable.
Aim on 2 hours from scheduled arrival time and you may be closer the right time before on the road. Anything less than that and you can drive away with a smug feeling of having done very well.
Good Luck
