Short answer: Mainland China generally does not recognise dual nationality; a Chinese national who settles abroad and voluntarily acquires a foreign nationality may be treated as having lost Chinese nationality, subject to public-security and consular practice. Hong Kong residents who naturalise abroad must manage HKSAR versus foreign passports, mainland travel permits and consular protection based on the resulting identity mix. Investment citizenship differs from residence rights: many golden visas grant residence only, not a foreign passport.
Common scenarios
| Scenario | Watch-outs |
|---|---|
| Mainland resident obtains foreign nationality | Home nationality, household registration and exit-entry documents |
| Hong Kong resident obtains foreign nationality | Choice of travel document; mainland travel permit |
| Foreign residence only | Usually does not change original nationality |
| Child born abroad | Jus soli and jus sanguinis overlap; case-specific filings |
Travel-document practice
Entering mainland China or Hong Kong on a foreign passport must follow border and visa/endorsement rules then in force. Do not assume a second passport lets you pick documents casually. Misuse has serious consequences.
Tax, service and succession
Nationality change can affect tax residence, inheritance and marital property. Some countries impose military service. Obtain dual-qualified legal advice before naturalising—not only mobility stories from migration agents.
Global Immigrate note
Separate goals of “foreign residence” versus “foreign passport.” If a passport is the goal, study home-country dual-nationality treatment and exit/retention procedures. Secure written legal opinions before major status changes.
