Yes, immigrants who have moved abroad can return to China, but the specific requirements depend on their current nationality and immigration status. Here is a summary of the key regulations and procedures:
1. Returning as a Chinese Citizen (Overseas Chinese)
If you retain Chinese citizenship (e.g., hold permanent residency abroad but not foreign citizenship), you qualify as a "Huaqiao" (华侨). To settle long-term in China:
Apply for a "Huaqiao Huiguo Dingju Zheng" (华侨回国定居证, Overseas Chinese Returning to Settle Certificate).
Required documents:
Valid passport and overseas residency proof.
Declaration of voluntary abandonment of overseas residency.
Proof of continuous residence abroad for at least 18 months in the last two years.
After approval, register for a household residence (户口) within six months.
2. Returning as a Foreign National (Foreign Citizen)
If you have acquired foreign citizenship, you are classified as a "Huaren" (外籍华人). Options include:

a. Apply for Permanent Residency in China
Investment Track: Invest in China for three consecutive years with stable operations and tax compliance.
Employment Track: Hold a senior position (e.g., VP, professor) for four years with at least three years of residency in China.
Family Reunification: Spouse of a Chinese citizen or permanent resident, married for five years, with five years of continuous residency in China.
Special Talent: Individuals with exceptional contributions to China.
Elderly Relatives: Parents over 60 with no overseas relatives, living in China for five years.
b. Short-Term Stay (Tourist/Business Visa)
Apply for a visa (e.g., L-visa for tourism, M-visa for business).
Duration: Typically 30–90 days per entry, extendable in China.
3. Restoring Chinese Citizenship
Former Chinese citizens may apply to regain citizenship:
Submit a written application, proof of previous Chinese nationality, and foreign passport copies.
Approval is granted based on "valid reasons" (e.g., family ties, career needs).
After approval, apply for household registration (户口) and an ID card.
4. Key Considerations

Dual Citizenship: China does not recognize dual citizenship. Acquiring foreign nationality automatically revokes Chinese citizenship.
Tax Obligations: Chinese tax laws may apply to income earned globally if you reside in China for over 183 days annually.
Original Country’s Residency Rules: For example, U.S. green card holders risk losing status if absent for over one year without a re-entry permit.
