Researcher Visa for US Scientists: Navigating Section 18d of the German Residence Act (AufenthG)
- 4 Minuten Lesezeit

Are you a US scientist considering relocating to Germany for research opportunities? Whether you plan to pursue a postdoctoral position, work on a specific project, or teach at a research institution, understanding the visa requirements and application process is crucial. The German Residence Act (AufenthG), specifically Section 18d, offers a clear pathway for international researchers to obtain a visa, allowing you to live and work in Germany while contributing to the scientific community. As a Berlin based Law firm with a lot of personal and professional ties to the United States we are happy to give you a comprehensive overview of the Researcher Visa in Germany.
Who Can Apply for the Researcher Visa?
According to Section 18d of the German Residence Act (AufenthG), the Researcher Visa is designed for individuals from non-EU countries, like the US, who wish to conduct scientific research in Germany. To qualify, you must meet the following criteria:
- Research Qualifications: You must have at least a PhD or an academic qualification that grants access to doctoral programs in Germany. This means that postdoctoral researchers, as well as PhD candidates, are eligible to apply.
- Hosting Agreement or Employment Contract: You need to have an effective hosting agreement or a work contract with a recognized research institution or university in Germany. This contract should outline the details of your research position, such as your responsibilities, compensation, and duration of stay.
- Financial Support: The research institution must confirm in writing that it will cover your living and travel costs for up to 6 months after the conclusion of your research project, unless your research is primarily funded by public funds.

Visa Benefits and Opportunities
The Researcher Visa offers several advantages:
- Research and Teaching: You can work at the research institution listed in your contract or take on a teaching position during your stay.
- Mobility within the EU: After obtaining the visa, you are permitted to conduct research and teach in other EU member states (except the Ireland, and Denmark) for a limited period.
- Extension: The visa is initially valid for at least one year, and it can be extended if you continue to meet the necessary requirements.
- Pathway to Permanent Residency: After living and working in Germany for four years, you may apply for a settlement permit (Niederlassungserlaubnis), which can lead to permanent residency.
- Post-Research Job Search: Once your research project ends, you have up to 18 months to find another job related to your qualifications in Germany. During this time, you may apply for a Jobseeker Residence Permit.

Special Considerations for PhD Candidates
For those seeking to pursue a PhD in Germany, the process is slightly different. If you are accepted for doctoral studies at a German university, you may apply for a residence permit under Section 16 of the Residence Act (AufenthG). However, if your research is part of an employment contract with a recognized research institution, you may be eligible to apply for the Researcher Visa instead.
The EU Blue Card as an Alternative
For highly qualified researchers with professional degrees and meeting certain salary thresholds, the EU Blue Card could be an alternative. The Blue Card allows skilled professionals to live and work in Germany and other EU countries, though it is subject to specific qualifications and requirements.
Application Process
To apply for the Researcher Visa, follow these steps:
- Prepare the Required Documents:
- Proof of your hosting agreement or employment contract with a German research institution.
- Financial proof that demonstrates your ability to support yourself (unless the research institution covers these costs).
- Proof of sufficient health insurance coverage.
- Passport and other required identification documents.
- Submit Your Application:
- Submit your application for the visa to the German embassy or consulate in your home country. It is recommended to apply at least 2–3 months before your intended travel date to allow for processing time (typically 5–6 weeks)
