Taiwan is tightening restrictions on immigrants from China to address fears of social division and infiltration by the Chinese government, which is perceived to be striving for unification with Taiwan. A notable case involves a young man living in Taiwan, who was notified by the National Immigration Agency that he would need to submit proof of his cancellation of Chinese household registration to continue residing in Taiwan. This new policy reflects stringent measures that have not been enforced for individuals who immigrated prior to 2004, raising concerns about the identity and loyalty of long-time residents.

The influx of Chinese immigrants to Taiwan began to increase significantly after 1987, following the easing of restrictions on cross-strait travel. Many of these immigrants have integrated into Taiwanese society, with the number of spouses from China reaching approximately 360,000. However, the Taiwanese government is increasingly wary of these demographics, fearing that they might be subjected to Chinese influence, which could undermine Taiwan's socio-political landscape and national identity.

This tightening of immigration policies highlights Taiwan's ongoing struggle with its identity in the face of perceived threats from China. As tensions persist, the government aims to safeguard its democratic values and social cohesion by managing the ties between its residents and their homeland. The call for verification of household registration reflects deeper uncertainties about who is considered a legitimate resident and the potential implications for future cross-strait relations.
