1. Confirm whether the registration information is correct: Check whether the accommodation registration information you provided is accurate, including the accommodation address and registration time. If there are any mistakes, correct them in time.
2. Contact the community or hotel where you stay: contact the staff of the community or hotel where you stay and ask whether the accommodation registration information has been reported to the exit-entry administration department of the local police station. If they haven't reported yet, please ask them to report as soon as possible.
3. Consult with the exit-entry administration department of the police station: personally go to the exit-entry administration department of the local police station to explain the situation to the staff and provide relevant proof materials for accommodation registration, such as accommodation contract and check-in registration form. Staff may help verify registration information or provide solutions.
4. Seek help from foreigners' service agencies: If the above steps can't solve the problem, you can consult local foreigners' service agencies and seek their help and guidance. They usually have more experience and resources to deal with similar problems.
