Immigration authorities arrested Carlos Portugal Gouvea, a visiting professor at Harvard Law School, after a BB‑gun shooting outside a Boston‑area synagogue on Yom Kippur. The State Department revoked his J‑1 visa; Gouvea accepted a plea and agreed to depart the U.S., the Department of Homeland Security said. Harvard placed Gouvea on administrative leave after the October incident; federal officials characterized the episode as an “anti‑Semitic shooting incident.” Local prosecutors declined to file a hate‑crime charge, and synagogue leaders told The New York Times they did not believe bias motivated the act. The case highlights campus safety, visa screening and reputational risks for institutions that host international scholars: universities must balance due process, campus protection and immigration law when incidents involve nonimmigrant academic visitors.
