What Sostrin Immigration Lawyers does

Sostrin Immigration Lawyers, LLP is a privately held, partner-owned immigration law firm headquartered in a single office at 21650 Oxnard Street, Suite 1408, Woodland Hills, California. Founded around 2010 and previously operating as Sostrin & Dgebuadze, LLP, the firm provides specialized legal representation in U.S. business immigration law and serves clients locally, nationally, and internationally, leveraging the federal nature of immigration practice to operate across geographies from one location. The firm employs between 11 and 50 people, including attorneys described as nationally recognized experts in specialized business immigration sub-niches.

The firm's core offering is organized around four practice areas: temporary work visas (H-1B, H-1B1, E-2, E-3, O-1, O-2, L-1, TN, J-1, P-1, P-3, and I visas), green card and permanent residence pathways (employment-based EB-11/12/13, PERM labor certification, National Interest Waiver, EB-5 investment, and family-based marriage categories), J-1 waivers (Conrad State 30, HHS, and hardship waivers), and naturalization/citizenship services. There is no proprietary technology product; the underlying stack consists of case management for immigration matters and standard law firm operations.

Revenue is generated entirely through professional services fees — typically hourly or flat-fee billing — for consultation and representation. The go-to-market is sales-led, direct client engagement through consultations, supported by a content marketing program (monthly newsletters dating back to 2017, publications, and client spotlights). The customer base spans six verticals: employers and professionals, healthcare institutions and physicians, academic institutions and researchers, artists and entertainers, investors, and families. The firm is structured as a California limited liability partnership with no external investors, no parent company, no disclosed subsidiaries, and no M&A, funding, or partnership activity in the available record.
