How long will it take for Tianjin's current commercial housing certificate to be completed! Do you need to bring any proof? What is the process? Thank you.

15 the earliest day, bring your and your spouse's ID card, household registration book, and household registration book where your household registration is located. Those who are demolished should bring the demolition agreement and the household registration book of the current temporary residence. These things should be copied and a hand stamp should be prepared for later use. First of all, you should take all these things and fill out the form in the Housing Authority. Then, a week later, you should stamp another income verification form of the Housing Authority and take it to the street for income verification. If you both have unemployment certificates, it's easiest not to have a job. If you have a job, take the street income verification form to fill in the unit, and then copy your verification form, ID card, unemployment certificate and household registration book to the street. It will be done in about 4 or 5 days. After the street office, take the income of the street office to verify and send it back to the Housing Authority, and wait another week to get the certificate. You should take your ID card and fingerprint to get the certificate. If you are not married, you should issue an unmarried certificate.
