The United States is engaged in mother immigration.

It's faster for you to immigrate first and then apply to your mother.

If your investment immigration goes smoothly (not a pit like EB5), you may become an American citizen in the next 5-6 years.

You can be qualified to apply for your mother, and you can help her complete the immigration formalities in a year or so.

If my mother immigrated first, I won't apply for you until she is naturalized. It will take about 10 years since I applied for you.
