Foreigners must get a housing registration form in China within 24 hours of arrival in the country. In most cases, a temporary housing registration form has to be filled in. If you live on the campus of a university or a hotel, go to the reception desk of your residence. If you rent an apartment off-campus, you must visit the local police station promptly with your landlord.
Please note that if you have renewed your passport or visa or changed your address, you must re-apply for a new housing registration form within ten days. Failure to comply with this requirement can result in hefty financial fines. Also, you will be regarded as an illegal resident.
