Capitol Law Partners - Istanbul
Address: Trump Towers, Residence 2901
Şişli, İstanbul 34381
Capitol Law Partners is a U.S. law firm with offices in Washington, DC, Virginia, New York and Minneapolis, and an Istanbul office that lets clients in Türkiye meet their American immigration attorneys in person and in Turkish. Every case is prepared under U.S. law by attorneys who practice before USCIS, the U.S. consulates and the federal courts.
Türkiye is a treaty country, so Turkish citizens can apply for the E-2 treaty investor visa by investing in a U.S. business, and much of our Istanbul work involves structuring that investment, forming the U.S. company and preparing the E-2 application for the U.S. Consulate General in Istanbul. We also prepare L-1 transfers for Turkish companies opening U.S. offices, EB-2 National Interest Waiver and EB-1A green card petitions for academics, physicians, engineers and entrepreneurs, F-1 student visas, and family-based immigrant visas processed through the National Visa Center and the consulate.
How our Istanbul office works
Consultations in Istanbul are held in Turkish or English. Petitions are filed with USCIS from our U.S. offices, and we prepare clients for their consular interviews in Istanbul or Ankara. When a visa is refused under section 214(b) or held in administrative processing under section 221(g), we review the refusal, prepare the reapplication, and where appropriate file a mandamus lawsuit in U.S. federal court to compel a decision.

Business counsel for Turkish companies entering the U.S. market
