Federal immigration authorities detained Ho Yin Mo, a field representative for California Assemblymember Catherine Stefani, at Harry Reid International Airport in Las Vegas on September 17, according to a statement from Stefani released on social media.
Mo, who has worked in Stefani’s office since January 2025, was taken into custody by U.S. Immigration and Customs Enforcement (ICE). The agency confirmed his arrest in a statement to multiple outlets, stating that Mo entered the U.S. in January 2020 on a temporary basis but illegally overstayed his visa by failing to depart by May 15, 2020.
Core Facts of the Arrest
ICE officials confirmed Mo’s detention in response to inquiries from Newsweek, The Epoch Times, and Fox News Digital. A spokesperson for the Department of Homeland Security (DHS) reiterated that Mo’s temporary visa status had expired and that he now faces potential deportation to Hong Kong, his country of origin.
Stefani, a California Democrat representing parts of San Francisco and San Mateo County, publicly called for Mo’s release in a statement shared on social media. She described him as a "selfless public servant" and a "valued, legal employee of the California State Legislature."
Mo’s Background and Career
Ho Yin Mo graduated from the University of California, Berkeley in 2020 with a degree in film and media, according to his LinkedIn profile. Prior to joining Stefani’s office, he worked as a news reporter at KTSF, a Chinese-language television station in San Francisco.
Mo later transitioned into politics, serving as a field organizer for former San Francisco Mayor London Breed’s 2024 reelection campaign, focusing on outreach to Asian American and Pacific Islander communities. He joined Stefani’s legislative team in January 2025 as a field representative.
Legal and Political Responses
ICE’s Stance: A spokesperson for ICE stated that Mo’s case is subject to due process through immigration proceedings. The agency emphasized that pending applications or work authorization do not confer legal status in the U.S., a point reiterated in communications with multiple outlets.
Stefani’s Advocacy: Stefani has publicly defended Mo, highlighting his contributions to serving Chinese-American constituents in her district. In her statement, she noted that Mo brings a "unique sense of belonging" to many in the community who recognized him from his time as a TV reporter.
Political Commentary: First Assistant U.S. Attorney for the Central District of California Bill Essayli commented on the case via X (formerly Twitter), stating, "No one is above the law, not even the California legislature and its staff."
What Happens Next?
Mo remains in ICE custody as his case proceeds through immigration court. The timeline for his deportation hearing or potential appeals has not been publicly confirmed. Stefani has not indicated whether legal or advocacy efforts are underway to secure his release or adjust his immigration status.
