A Taiwanese actress who publicly said she was giving up her Taiwan household registration for Chinese citizenship has quietly come home to run for New Taipei City councilor, raising fresh worries about Chinese influence inside Taiwan's elections.

• Chen Chu-yin, who moved to China in 2022 and said she would drop her Taiwan residency and health insurance, has registered as a Labor Party candidate in New Taipei.
• Election officials say she is eligible, because she never appears on the list of China-linked people barred from running and now says she never obtained Chinese residency.
• Yeh Yao-yuan, a professor at the University of St. Thomas, calls this the most dangerous case: she keeps her Taiwanese citizenship and full political rights, so nothing stops her unless money trails can be proven.
• The worry is that Beijing uses Taiwan's own democratic system to push an anti-democratic agenda, with a left-wing party leaning toward China rather than defending Taiwan's sovereignty.
• Laws to counter Chinese infiltration are stuck, with the legislature gridlocked and the KMT pushing back against any such bill.

Outlook: Expect the case to fuel a louder fight over anti-infiltration laws heading into Taiwan's 2026 local elections, with little chance of new rules passing soon.
