This Friday, my girlfriend is coming to Denmark via Oslo on a flight originating in New York (EWR). I'm not sure on how it actually works in terms of her getting a visa. We have plans to travel to Brussels for a weekend while she is here, flying Ryanair, but they require a special visa check for non-EU travelers:
You must go to the visa check/bag drop desk and have this document stamped before proceeding through security.
Is she issued the visa as a stamp in her passport when she goes through passport control in Oslo, or would this happen in Denmark (or some other way)?
What exactly does Ryanair expect, to prove you have a visa?
