About GSC International
Editorial summary
GSC International is most relevant to clients comparing several mobility routes alongside cross-border business or structuring needs. The firm publishes a five-office network and a dedicated citizenship, residency and global-mobility division; programme details should still be confirmed against current government rules.
GSC International describes itself as a boutique global law firm serving companies, institutions, investors and private clients for more than 20 years. Its website lists offices in Paris, Budapest, Bratislava, Istanbul and Dubai, with additional partner locations. The firm’s Citizenship & Residency by Investment | Global Mobility Solutions division publishes coverage across Europe, North America, the Caribbean and Oceania, including Portugal, Greece, Malta, Hungary, Türkiye, the United States, Canada, Antigua and Barbuda, St Kitts and Nevis, Panama, New Zealand and Nauru. The public team page lists 18 people, led by managing partner and Istanbul Bar member Onur Sümer. GSC also identifies Murat Bozfakıoğlu, based in Dubai, as leading its citizenship, residency and global-mobility division. An independent March 2026 IMI profile describes GSC as an industry partner with a 20-year cross-border legal practice and roughly 15 mobility-program jurisdictions. Programme requirements can change, so this directory does not repeat investment thresholds or processing-time claims without primary-source confirmation.
