Tangentially related, but I work for a New Zealand company that does civil engineering work, including some in the US. There's a lot of localization that we have to do around roads being much wider and different materials being used, but the main idiosyncrasy is that in New Zealand we can just call people up on the phone or via email and arrange contracts, but for large jurisdictions in the US there is a competitive bidding process that we (as a foreign company) can't just circumvent.
My boss wanted to investigate some sinkholes on the runway at LaGuardia to calibrate a device, and was confused that I (the token American) couldn't just call up the Port Authority of New York and get our truck of equipment onto a runway the same week. I tried to explain to a coworker that American airports and the Port Authority in particular are very sensitive about what they allow airside, and he said "oh, so we don't get hit by a plane." I had to explain the last 25 years of American history to him.
