There are two disadvantages, 1. If you want to apply for a driver's license around the school in the future, then you are a foreigner and the price of driving school will be higher. 2. If you want to develop in the place where your school is located after graduation, and some applicants need local hukou, then you are a foreigner, and you have not changed your hukou, so you are not eligible to apply.

There are several advantages, 1. When you go home to find a job after graduation, you don't have to change your hukou, so graduation is not so troublesome. Because of graduation, your school account will be transferred back to the local area. 2. Rural hukou can enjoy rural medical cooperative insurance, and a large amount of expenses can be reimbursed when sick.

Think for yourself, my situation is the same as yours, but I didn't change my hukou when I went to college, so it's very troublesome to transfer, and it's also very troublesome to transfer back after graduation.
