| This passport has the rudest, least helpful, least polite staff in the USA. When my husband and I arrived at passport control, the guy asked us how long we were staying. We answered that we were residents with a visa. Very sarcastically, he replied "No you're not! What does it say here?" (pointing at our passports cover, as if we were unable to understand). It says "United Kingdom", not "United States". We tried to reply that we actually live in the USA and we have visas that allow us to do so, but he wouldn't have it. "Again (as if he were speaking to one year olds), what does it say here? "United Kingdom". You are not citizens". He repeated this several times, without listening to us. Knowing that, unfortunately, he could potentially be spiteful and delay our entrance to the country indefinitely (and our dog is here, so at least we wanted him back!), I had to restrain myself and just reply: "We are residents, we never said we are citizens. We live here and have done so for four years now". Finally, the penny dropped. "Ah, yes, there's a difference". And that was all. No apology for treating us like children, for his smugness, rudeness, or his mocking attitude. I can understand he can make a mistake, but it's unforgivable that he should have that attitude without even having listened to us. He treated us like we were having a hard time understanding anything, when in fact it was him who was misunderstanding the situation (and not making any effort to get the facts before answering with his stupid arrogance). It's always a shock to come back to O'Hare, as anywhere else staff is friendly and helpful. Every single time.
