A Democratic Progressive Party legislator yesterday introduced a draft amendment that would require Chinese spouses to swear an oath of loyalty to Taiwan and take a test of civic knowledge before becoming citizens.

Legislator Huang Jie (黃捷) proposed the changes amid controversy around a proposal to allow Chinese spouses to obtain citizenship after four years of marriage, down from six.

Under the proposal, the oath of loyalty would be legally binding, with contravention of it resulting in the person losing their household registration.
