My relative, a young student and mother, was travelling to visit me in Scandinavia from Africa. She had a legal visa issued for medical reasons. When she arrived in Germany in transit, she was asked to show a return ticket. She had this but, since it didn't have any return information, she could not prove that she had it.
Neither could she show the doctor's letter because those documents had been given at the Embassy at the time of visa being issued. This led to hours of being interrogated like criminal by teams of officials, strip naked and all body parts probed by immigration officials.
Meanwhile, nobody informed us that this was happening. When they finally called, it was to inform us that her Schengen visa had been annulled and she was to be removed the next day, that she had lied about why she obtained her visa, but that she could appeal the decision.
At the time of visa issue, they had no doubt about her returning because all the documents asked for were provided.
What is the best course of action to clear her record, get another visa and travel for the doctor's appointment? Should she appeal or should she get a new passport (because it has the vis annulled and its damaged as) and apply again?
What about the pictures they took of her and information recorded about her? Does it not accuse her, in spite of her innocence? Can she file a complaint for humiliation and psychological torture?
