Dr. Nieves Castro is not a USCIS-designated Civil Surgeon and does not personally perform immigration medical examinations. Her role is to review this site's general medical content — vaccine information, screening explanations, and related health topics — for factual accuracy. Immigration Medical itself is a referral network: we connect applicants with independent, USCIS-designated Civil Surgeons in their own communities. See our Civil Surgeons page for how those providers are vetted.
