A dedicated immigration practice in Berlin

SERS is a boutique firm built around a single, in-demand specialism: helping individuals, families and businesses navigate the German immigration system. From its Berlin office, the firm advises on the full spectrum of matters that arise when people seek to enter, live and settle in Germany, including short-term visas, long-term and residence visas, naturalisation and citizenship, and asylum applications. This focus allows the firm to develop deep expertise in the procedures and evidentiary requirements that determine whether an application succeeds.

Germany is one of Europe's most important destinations for skilled workers, students, entrepreneurs and families, and its immigration framework is correspondingly detailed. The Aufenthaltsgesetz (Residence Act) and related regulations govern residence permits, the EU Blue Card for highly qualified professionals, family reunification, permanent settlement, and the pathway to German citizenship. Requirements frequently involve coordination between German embassies abroad and the competent domestic authorities, and unfavourable decisions can be challenged before the administrative courts. A specialist firm that understands both the substantive law and the practical realities of dealing with the Ausländerbehörde and consular posts can make a decisive difference to applicants.

Services for individuals, families and businesses

SERS supports clients across a wide range of immigration goals. These include visas and residence permits for employees, highly qualified professionals and companies; routes for students and interns; family reunification; naturalisation; and asylum procedures. The firm is oriented toward an international clientele, reflecting Berlin's status as a global city that attracts talent and investment from around the world. By concentrating on immigration alone, Surin Ersöz and the SERS team are able to guide clients efficiently through complex, document-intensive processes, anticipate obstacles, and represent applicants before the authorities and, where necessary, the courts.

Why specialist immigration counsel matters

Immigration outcomes often turn on precise compliance: the correct visa category, complete and properly translated documentation, adherence to deadlines, and a clear legal basis for the application. Errors or omissions can lead to refusals that are costly and stressful to reverse. For skilled workers and their employers, delays can jeopardise start dates and business plans; for families, they can mean prolonged separation. A firm focused solely on this field can offer the clarity and reliability that clients need, translating a demanding legal process into concrete, actionable steps.

A trusted name for international clients

As a firm serving an international clientele from the heart of Berlin, SERS understands the concerns that accompany a move to a new country: the need for certainty, clear communication and a reliable timeline. Surin Ersöz, who advises on immigration for both Germany and Spain and holds an LLB in European Law, brings a genuinely cross-border European perspective to the firm's work. Whether a client is a skilled professional relocating for a new role, an entrepreneur seeking to establish a business presence, a student pursuing studies in Germany, or a family working toward reunification and eventual naturalisation, the firm provides tailored guidance at every step. This client-centred, specialist approach is precisely what has distinguished SERS in the German immigration market.

Leadership and recognition

As founder and CEO, Surin Ersöz has positioned SERS as a trusted name in German immigration law, serving clients seeking to work, study, invest, reunite with family or build a future in Germany. The award of Immigration Law Firm of the Year in Germany — Corporate INTL Global Awards 2026 recognises the firm's specialist standing and the quality of its client service. Corporate INTL's awards identify advisers who demonstrate consistent excellence within their jurisdiction and practice area, and this honour affirms SERS's reputation in one of Europe's most significant immigration markets.

For anyone confronting the German visa, residence, citizenship or asylum system, SERS Immigration Law Firm Germany and Surin Ersöz offer focused, experienced guidance from a Berlin base, combining knowledge of German and European law with a practical understanding of how to achieve results for international clients.
