Why the VISA warning file is a mess at Metronaut.de – Big Berlin Bullshit Blog. The VISA warning file affects me directly and personally. My fiancée is Russian, her family still lives in Russia, and we will continue to make and want to make visits. I can already say goodbye to any illusion of data protection for myself and Juliana. Of course, a state has the right to protect itself from abuse, but general suspicion solely based on the use of legal possibilities is always wrong. And the VISA warning file is nothing more than the general suspicion of citizens simply because they appear once in the context of a visa application. This has nothing to do with the rule of law anymore.
