On the issue of immigrant household registration and over-age

First of all, your grandmother will receive an I797 approval notice when applying for your home. There is a date in the upper left corner. How old are you when you look at that date? If you are under the age of 2 1 year on this date, you may be eligible for immigration through appeal.

Second, the complaint letter should be written to NVC, that is, the American visa center, which can be written by a more reliable intermediary in the United States. I have to write two letters, one to NVC and one to Guangzhou Consulate.

Third, if you have no choice, you can only ask your mother to apply for you when she comes to America. The requirement is that you can't get married before you get a green card, otherwise the application will be invalid.

As for the hukou, it doesn't matter. You are 2 1 year old now, and you don't need a guardian. So those domestic problems are irrelevant.
