So the following conversation took place at Gatwick Airport in April 2015, around 10:30PM, as I was entering the UK on a Swedish ID card. I was dressed in jeans and a plain red t-shirt (it was warm outside), had a laptop bag for hand luggage and was sober.
(I look southern European, perhaps Bulgarian, and speak Estuary English - basically like Gordon Ramsay accent-wise)
IO: Where are you arriving from?
IO: Where are you headed to?
IO: What will you be doing in London?
Me: Just visiting
IO: For how long?
Me: A week
IO: Where will you be staying?
Me: At a hostel in Dollis Hill
IO then looks at my ID and scans it with a UV lamp. After 30 seconds…
IO: Do you have another document?
Me: Er, such as?
IO: Dunno, bank card, library card, driving licence, anything.
Me: Nothing with a photograph I’m afraid, but here’s my debit card (handing in my Maestro card)
10 seconds later...
IO: How come you’ve got a Swiss bank card!?
Me: Because I live and study in Switzerland, in Zurich
IO: Since when?
Me: Autumn 2014
IO: What do you study there?
Me: Computer science, at the federal institute of Technology
IO: Towards what degree?
IO scans the ID, and 30 seconds later...
IO: Alright, have a good evening.
The question in bold is among the weirdest questions I've received from immigration anywhere, although thinking about it, I suspect the officer had her doubts about me actually being an EEA national.
Is this the likely reason for the unusually long landing interview (for an EEA national)?
On some previous occasions I've cleared immigration at the same airport, under identical circumstances, without a single question.
