I am a US citizen who recently moved to Munich, Germany to study for a semester. I am in the process of applying for residency. I do not yet have a residency card and have been here less than 3 months, all I have is a paper saying that I have a registered address in Munich. Can I buy a Interrail pass? What extent of proof do I need of my residency?
If I buy it now, can I wait to activate it until I get an official residency card or does the term start the moment I make the purchase?
