At present, the cost of living in California is about 1.5 times that in China.
The most critical issue is that children under 2 1 year old cannot apply for their parents' green cards. Parents who accompany them to the United States can only use visiting relatives or tourist visas. The time is limited and they will leave when they expire. Moreover, if your child holds a green card, you may be inclined to immigrate and you may not get a visa. At that time, the so-called 13 free compulsory education was all on paper.
In addition, although the United States also has the concept of school district housing, you can study as long as you rent a house in the school district, so this is much stronger than in China.
If you have any other questions, you can consult the New Jersey Governor and the American Moon Center.
