Even if you move your hukou to Beijing, you can only put it in your university. Four years later, when you graduate and look for a job,
If a unit in Beijing is willing to solve your account problem and accept your account, then you can change your Beijing account. Of course, many units will not accept your account and help you solve the account problem.
If you choose to go back to your hometown instead of looking for a job in Beijing, your account will be transferred back to Tianjin. A lot of people have lost their hukou when they move back, making you a black household. ) If you are from agricultural registered permanent residence, your graduation account will be automatically changed to non-agricultural registered permanent residence after you move back, and you will lose all the benefits of agricultural registered permanent residence. To put it simply, if your original household registration belongs to the village, you can't go to the village after you transfer back, but you can only return to the non-agricultural household registration in your town or township.
If you move your hukou to Beijing and put it in your university, you won't enjoy the preferential treatment of Beijing citizens. The state does not have this preferential policy. This is our experience. You can decide when to move. My advice is not to move. I hope it works for you!
