I have a valid D-visa for another couple of months. I have been living in Germany for less than 90 days, but that will soon go over the 90 day limit.
I have been unable to find an appointment for a residency permit even though I have been trying for weeks. I have already submitted an email application through the contact form with all my documents. The documents I sent include - the official form (filled out), german health insurance, anmeldung of apartment, blocked account confirmation, educational institution registration.
I have the confirmation of the sent email saying it counts as an application but the language is a bit vague around extension vs. applying for a brand new permit.
The confirmation says -
Wenn Sie in Ihrer E-Mail die Verlängerung der Gültigkeit Ihres befristeten Aufenthaltstitels (Aufenthaltserlaubnis, Blaue Karte -EU oder D-Visum für einen längerfristigen Aufenthalt) beantragt haben, gilt hiermit Ihr Aufenthalt im Bundesgebiet (mitsamt den Nebenbestimmungen Ihres jetzigen Aufenthaltstitels) bis zur Vorsprache im LEA als rechtmäßig. Das bedeutet, Sie können weiter im bisherigen Umfang arbeiten oder studieren.
If you have applied for the extension of the validity of your temporary residence permit (residence permit, EU Blue Card or D visa for a longer-term stay) in your email, your stay in the federal territory (including the additional provisions of your current one) is hereby valid residence permit) as legal until the LEA interview. This means that you can continue to work or study to the same extent as before.
However this is not an extension of a pre-exisiting residency permit. This is an application for my first residency permit.
Can I stay in Germany beyond 90 days as long as I have the email letter and my visa is still valid for a few months? Even though I have not yet gotten a residency permit, a residency permit appointment, or a Fiktionsbescheinigung?
Also as a separate but related question - Can I travel Europe using this visa? It only says Deutschland and not Schengen. Does the 90/180 rule only apply to countries that are not Germany, or does living in Germany also count towards my 90 "days" of allowed stay within Europe?
