In general, when applying for a one-year extension of a residence permit, the final extension period is usually one year and will not exceed one year, but there may be special circumstances. Here is a specific introduction:
Conventional situation
According to the provisions of the Law of the People’s Republic of China on the Administration of Exit and Entry, aliens who apply for extension of residence certificates shall submit an application to the exit and entry administration of the public security organ of the local people’s government at or above the county level in the place of residence 30 days before the expiration of the validity of the residence certificate, and submit relevant materials as required. If applying for an extension of one year and meeting the conditions, it is usually extended for another year starting from the expiration date of the old residence permit.
exceptional case
Limitation on the validity period of the work permit: if the foreigner holds a work permit, the extension of the residence permit will generally expire at the validity period of the work permit. Even if the application for extension is for one year, if the validity period of the work permit is less than one year, the extension period of the residence permit will be shortened to the validity period of the work permit.
Policy changes or special regulations: During certain special periods or due to specific policies, there may be different regulations regarding the extension of residence permits. During the epidemic prevention and control period, the expiration of residence permits in some areas will be automatically extended by 2 months.
