Yeah it is horrendously complicated for different nationalities! I've only ever had to provide a scan of my passport to employers in order to prove I have a right to work. Never had to do that when renting. I bought a house recently, so proper ID checks were part and parcel of that (but that was the same for my British wife).

9 years ago you would not even be accepted into a pub in the UK if you only had a EU ID card with you. Not so sure about today as I’ve got a UK driver’s license not to bring my passport with me.
