It is stipulated in relevant Chinese laws that when foreigners come to China, their temporary residence changes should be reported to the visa provider in a timely manner (within 24 hours). When foreigners come to China, they can enter and stay in China only with valid passports and corresponding visas. Foreigners who rent a house shall specify or change their temporary residence. Foreigners themselves shall report the change to the visa provider or relevant competent authorities within 24 hours. Reporting this change means that foreigners and landlords should go to the public security organ where they live, provide valid certificates and documents, and handle residence certificates. It can be seen that in order to obtain the Alien Residence Certificate Registration Form for Foreigners issued by the Chinese public security organ, at least valid passports, legal visas, residence contracts and property certificates must be provided. According to the Regulations of the People's Republic of China on the Administration of the Entry and Exit of Aliens, if foreigners rent a house, it is necessary to clarify or change their temporary residence. Foreigners themselves should report the change to the visa provider or the relevant competent department within 24 hours. Reporting this change means that foreigners and landlords should go to the public security organ where they live, provide valid certificates and documents, and handle residence certificates. Article 10 Aliens who, after entering the country with visas, may change the reasons for their stay or provide entry facilities according to the provisions of the State, or who need to stay in groups due to objective reasons after entering the country with new passports or group visas, may apply to the exit and entry administration of the public security organ of the local people's government at or above the county level for a new visa. Article 13 If an alien's application for visa extension, renewal, reissue or application for a residence permit meets the acceptance requirements, the exit and entry administration of the public security organ shall issue an acceptance receipt with a validity period of not more than 7 days, and make a decision on whether to issue or not within the validity period of the acceptance receipt. 1. House lease contract. 2. House ownership certificate or other legal ownership certificate (original and copy). 3. Identity certificates of both parties to the house lease (original and copy). 4. Household register of both parties to the house lease. 5. If the public housing is subleased, the lease contract of the public housing shall be provided, and the written agreement signed between the sublesser and the lessor shall be provided; In case of sublease of other houses, the registered housing lease contract and the written certificate of the lessor's consent to sublease (original and copy) shall be provided. If the lessor entrusts an agent, the lessor's power of attorney and the agent's identity certificate (original and copy) shall be provided. Then let's extend this question to the following: Article 25 of the Regulations of the People's Republic of China on the Entry and Exit of Aliens is illegal residence in China if an alien has one of the following circumstances: (1) stay and stay beyond the period of stay and residence specified in the visa and residence permit; （2） Foreigners who enter the country without visa stay beyond the visa free period and do not apply for residence permit; （3） Foreigners who live in areas beyond the limits; （4） Other situations of illegal residence.
