How to immigrate a mother and 12 year out-of-date sister together lacking waiting 10 years?

Both the mother and the sister are here in the USA on visitor visas.

Apparently, getting the mother in is legally short wait time (a few months)

But the sister has an average wait in a minute of 8 - 10 years. Problem is, she is very young.

Is there any trick to speed this up? Or find another passageway?

We thought about getting her on a student visa (F-1) but then she would still need to take off the country to get it; and, apparently junior high schools within our state do not accept F-1's. So missing school for a couple of years is not a good perception.

The only other option I know of is to get the mother her green card first, and after get it for the daughter using the mothers permanent residency status. but that could still take 1 - 2 years base on average current wait times, and I dont know the real liklihood of that particular scenario.

What else can I do to find a snatched solution to get both the sister and the mother here, preferrably both with green cards?
Answers:   
your mother can change her status within the us, but your sister needs to go back to her country and hang about for your mom to have her green card. right now the INS is processing june 2004 for all countries except mexico sept 2001. and just this minute the processing date move about a month every two months. you can google "visa bulletin" for the date. hope this helps.
There is no quicker solution under the current laws. What you own found is the system as it stands. And F-1 visas are for college generally. If they are used for junior or senior high school, YOU own to pay the school district what the school district get per student. This could be $10,000 a year for tuition. You do not get free education on a student visa unless you are in grad university and are doing really useful research for the school.
I'm pretty sure the only opening is for her to leave the country and go through the legal process from near. In the long run it would be worth it. Otherwise she will be here illegally and when she is caught she would be deported.
