Official Expert Answer
Most people do *not* recommend parallel Approbation applications, because authorities may require exclusivity or at least clear communication, and you can create confusion about which file is “active”. Also: you’d need duplicate certified copies (expensive) and the processes can conflict. Better alternatives to reduce waiting pain: • Ask for a completeness check and missing-doc list in your current Bundesland. • If moving is realistic, plan a clean transfer (Aktenübernahme) instead of two parallel files. If you still want to do it: ask the current authority first if it’s allowed and what the consequences are. Don’t surprise them—bureaucracy hates surprises.
