Or is it too risky?
To clarify, I’m looking to extend my current student visa since I’m starting another degree here, and I emailed them according to instructions on this page: [https://www.berlin.de/einwanderung/termine/termin-vereinbaren/artikel.1144332.php](https://www.berlin.de/einwanderung/termine/termin-vereinbaren/artikel.1144332.php)
It says there that while my stay in Germany is legal, “in case you wish to travel abroad: you are not allowed to re-entry Germany”. I’ve been told by frequent travelers that there’s no way they’ll check my passport in and out of Germany if I do by train, but I’m worried.
