What CS LAW | Your Rights . Our Mission does

CS LAW (Calderón Seguin PLC) is a privately held, single-office law firm headquartered in Fairfax, Virginia, founded in 2014 by partners Ofelia L. Calderón and Scott Seguin. The firm operates as a six-attorney boutique (three partners, three associates) serving individual clients throughout the DC metropolitan area, including Northern Virginia, Maryland, and Washington DC. Its core offerings span four integrated practice areas: immigration law (visas, green cards, asylum, naturalization, detention and removal defense, appeals), crimmigration (defense of non-citizens in criminal matters, post-conviction relief, pardons, expungements), criminal defense (Virginia state and federal court representation across the offense spectrum), and family law (divorce, custody, support, prenuptial agreements, protective orders, and SIJS). The firm's positioning is built around the deliberate intersection of these practice areas — particularly where criminal charges affect immigration status or family matters intersect with immigration relief — which few competing firms in the region replicate. Calderón holds a Martindale-Hubbell AV rating, has served as Past President of the Hispanic Bar Association of Virginia and DC chapter chair of AILA's liaison committee to EOIR, and partners engage with Legal Aid Justice Center and CAIR Coalition on pro bono immigrant representation.

The business is a professional services practice operating on a direct-to-consumer motion. Fees are quote-based, set during initial consultations based on case complexity, and the firm publishes no standard fee schedules. Clients reach the firm through referrals, organic search, online contact forms (with practice-area and attorney-preference selection), and direct phone or in-person contact at the Fairfax office. There is a single physical office at 2751 Prosperity Ave #500; existing clients also pay via a LawPay portal. Demand generation combines community-embedded marketing (pro bono work, advocacy-organization partnerships, bilingual Spanish-language delivery) with educational content marketing via an active blog published throughout 2025-2026. Revenue streams are entirely fee-for-service legal work, with no disclosed revenue figures, no external funding, no parent company, no subsidiaries, and no M&A activity in the source material. The firm competes on domain specialization in crimmigration, reputation layered by multiple peer-reviewed awards (Super Lawyers, US News Best Law Firms, Washingtonian Top Lawyer, Best Lawyers, Northern Virginia Magazine), and strong community ties — rather than on technology or scale advantages — making it a relationship-intensive, talent-led practice rather than a platform business.

Core offering

CS LAW is a private law firm offering integrated legal representation across four practice areas: immigration law, crimmigration (the intersection of criminal and immigration law), criminal defense, and family law. The firm serves individual clients in the Washington DC metropolitan area and beyond, with particular expertise in cases where criminal charges affect immigration status or where domestic matters intersect with immigration consequences. Attorneys represent clients across immigration court, criminal court, and family court with a unified strategy.

Product overview

CS Law (Calderón Seguin PLC) is a law firm offering integrated legal services across three interconnected practice areas: Immigration Law, Crimmigration (the intersection of criminal and immigration law), Criminal Defense, and Family Law. The firm is structured as a unified service offering rather than a platform with modular products, where attorneys work collaboratively across practice areas to address complex cases where immigration status intersects with criminal charges or family matters. The core practice areas function as integrated service lines that share attorneys and cross-refer cases to provide comprehensive representation.
