On the question of mother's immigration, when can children immigrate to the United States?

1. If the application is submitted in China, the fastest time is 4 months and the slow time is 8 months; If submitted in the United States, several months to 1 year.

2. Have a green card in the United States; Marriage immigrants can apply for citizenship after 3 years.

You are over age, so you need to arrange your application anyway. If you have never been married during this period, you can apply for your mother's green card, which is the second priority (up to 7 years); If your mother becomes a citizen, you will be transferred to the first priority (about one year); If you are married, you can only apply after your mother becomes a citizen, which is the third priority (about 3 years). Either way, it is calculated in a few years, so be prepared for a protracted war.
