Yes. Researchers with particular expertise, instructors and prominent research staff may be permitted to stay for an indefinite period under the settlement rules.
The researcher route can lead toward permanent residence. The official material notes that researchers with specialised expertise, instructors and prominent research assistants may be allowed to stay for an indefinite period.
This indefinite right falls under Germany's settlement provisions rather than the temporary researcher permit itself, and it depends on meeting the relevant conditions. If long-term settlement is your goal, look into the settlement permit criteria early and keep records of your research achievements and qualifications, which can support such an application.
