Can Hong Kong residents obtain citizenship in a country other than China?

Yes, Hong Kong residents can obtain citizenship in a country other than China. The Nationality Law of the People's Republic of China does not recognize dual nationality ¹. However, the legal system in Hong Kong is separate from that of mainland China, so Hong Kong permanent residents with Chinese ancestry may still obtain foreign nationality ². Non-Chinese Hong Kong permanent residents may apply for a travel card that allows them to visit mainland China, but they cannot obtain a Hong Kong SAR passport ³.
