What Ellis Porter does
Ellis Porter is a private US immigration law firm founded in 2003 and headquartered in Michigan, with offices in Troy and Ann Arbor. The firm operates as Ellis Porter PLC with a wholly-owned UK subsidiary (Ellis Porter UK, Ltd) established in 2019 to serve UK-based corporations and individuals seeking US immigration pathways, giving it a transatlantic footprint uncommon for mid-sized immigration boutiques. Its practice is organized around six service lines: business immigration (temporary work visas, employment-based green cards, employer compliance), individual and family immigration (family reunification, citizenship, asylum), high-skilled professional visas (EB-1, NIW, O-1), healthcare immigration, sports immigration (including esports), and US expansion services for international companies entering the US market.
The firm's underlying infrastructure consists of immigration law practice management and case tracking systems supporting visa applications, green card processing, and immigration compliance work; there is no proprietary technology product, no public API, and no disclosed AI or machine-learning capability. Service delivery is sales-led through direct attorney consultations, either in-person at firm offices or remotely, with lead generation supported by content marketing (immigration news blog, webcasts), AILA membership, and partnerships with RSM, the UK Department for International Trade, TechTown Detroit, and Global Detroit.
Revenue is generated on a professional services model through legal fees for immigration matters; pricing is quote-based and not publicly disclosed. The firm employs 101-250 people across multiple partners and senior attorneys, some of whom carry Big Four accounting firm experience. Ownership is founder/management-controlled — Marc Topoleski serves as Founder & Managing Partner — with no external venture capital, private equity, or institutional investment evidenced in available materials.
