I am an Australian citizen and currently live in Germany. I have an Aufenthaltserlaubnis (limited residence permit) valid until the end of my PhD contract. I am planning a research visit to an institute in France, however, for longer than 3 months. During this time, I will still be enrolled at my institute in Germany, and be paid by them (and by extension, still pay german taxes / social security).
Is this possible with the German residency permit (Aufenthaltserlaubnis), or would I additionally need to apply for a residence permit in France? I was not able to find any information online - using this website https://france-visas.gouv.fr/en_US/web/france-visas/ and inputting an Australian passport, it says I need a visa unless I am 'A foreign national who holds a long-term resident permit-EU from a state of the European Union'. However, I am not sure if the Aufenthaltserlaubnis counts - it is a long term residency permit, but it has an expiry date.
