If a visitor intends to stay in Guangzhou longer than the duration of their visa, they must apply for residency abroad. The process for obtaining residency first requires an applicant to obtain a physical residence permit from a Chinese embassy, consulate, or public security agency. The applicant must submit a valid passport, visa, and other necessary documents to demonstrate identity and reason for residency.

Once all necessary documents are approved, the applicant will received the relevant residency permit and can legally stay in Guangzhou," mentioned another expat when asked about moving to Guangzhou, China.
