German border guards at Frankfurt airport detain Russians who arrive at the airport with new visas of other countries (without entry stamps in their passports) and fly in transit.
Here is an example: a Russian was flying from Turkey to Germany to Spain with a newly obtained Greek visa. In Frankfurt he was fined 400 euros, had a special mark put in his passport and was deported to Istanbul. He did not have to cancel his visa.
The story ended well, and the young man flew from Istanbul to Greece, and from there to Spain, where he had already begun his studies.
The relatives of the hero of this story were particularly angered that he was given not only a C mark (without a visa or residence permit), but also an I mark, which means “Danger to public order and internal security. Since he did not violate public order, the only version is that he was tagged because he was Russian. The Germans did not give him his passport, so they could not appeal against the marking on the spot. The Russian’s passport was given to him by pilots in Istanbul.
Initially police officers explained that the problem was that the country of first entry with Greek visa was Germany. Now in Europe, first-entry controls have become stricter. And this is not the only case, Russians encountered the same problems in Amsterdam
