My wife was inviting a friend from a Visa country, a holder of a 1 year multi-entry visa to Finland, to come to Germany to stay with us for a week. It seems that immigration at Frankfurt airport insisted on seeing an official invitation. You know, that document where you have to get from the Auslanderamt by showing proof of income, registration, etc.
I thought that once you had a Schengen visa and had used it the first time to visit the issuing country, you could go anywhere in 'schengenland' and the only thing that immigration could do is to demand evidence of ability to support yourself? Given that the official form is a pain to organise (mostly taking time off work and queueing), is this actually correct? I know you need the 'official' invitation if you are inviting someone and they are applying to Germany for a visa, but if they already have a Schengen Visa?
