Yes, your mother can sponsor you. It currently takes a little over a year. If your mother sponsors you now, and you turn 21 during the USCIS processing, you may still qualify under Child Status Protection Act (CSPA). There is also a chance that you were eligible for the green card when your mother got it. To ensure that you qualify, to ensure that everything is done correctly and timely, you and your mom need to consult with a lawyer as soon as possible. Good luck!

That category depends on whether your mother is a citizen or permanent resident. It also depends on whether you are here in the USA or abroad and if here in which status. F2A category, BTW, is now current which means you are ready to go if your mother is an LPR. IF she is a citizen you had been ready to go since she became one. Ask her to talk to an immigration lawyer immediately.

The timing depends a little on where you reside and which district office will handle your case. If you are under the age of 21 when the application is filed and hopefully adjudicated, you should fall under the immediate relative category. You should seek experienced counsel to make sure this is all done properly and timely.
