The InterRail site states that InterRail pass is not valid in my country of residence. How do they determine my country of residency?
I'm working in Germany, so from Germany's view I'm a German resident. But I have a permanent registration (meldunek) in Poland and that's the address that is on my personal ID. So if I'd have to proof my permanent residence in the other country, it would by Poland.
So in which countries can I use InterRail? Can they forbid me using it in both Germany, claiming I work there, and Poland, where I'm registered? Or I can 'choose' my country of residence, because I could proof my residency in both countries?
Just to make it clear: I could prove my residency in Germany by having with me the German registration, the work contract, the health insurance etc. and make my life complicated to be granted a right to pay extra for the trains in Germany, but it's not my point. I ask, what documents I am required to prove my country of residence? What is the minimal subset?
Is the country of residence where I have permanent registration? If so, it's Poland, because it's on my personal ID.
Is it the country of shipment of InterRail? Seems to be very simple rule to check. Then it's Germany where I live.
The problem is, the FAQ gives no clue how the 'country of residence' is applied for expatriates, in context of InterRail internal regulations (not the EU civil law etc.).
