As the Title says, which countries ask (a lot of questions) of returning citizens? In Canada, I'd be very surprised if a Canadian citizen was not asked at least one single question by the frontline customs officer (places travelled t and purpose of trip). I think U.S. citizens are similarly asked at least a question or two by B.I.C.E. officers?

By contrast in Europe, it seems immigration officers of E.U. member countries rarely if ever ask any questions of their returning citizens (or citizens from another E.U. country) and of course customs officers are seldomly seen. I['ve heard it claimed that immigration officers have no business other than to match your travel document to yourself, and admissibility to the E.U.

What other countries make this list?
