My path to becoming a CRNA... am i doing it right?

Hi all! I am fairly new to allnurses.com and to nursing altogether. I have found myself in a predicament. Let me explain my situation, I am 19 years old, im a south african living in the U.S (California), i am not a citizen but i have a student Visa. My family and i had immigrated to the country 2 years ago as there is a shortage of pharmacists and my dad was recruited. This seemed like a good way for us to get our green card. The problem is that my father passed away 2 weeks ago, meaning that my mother might have to move back to South Africa along with my sister, but i can stay along with my brother and study with our student visa's. My priority is to stay in the U.S. We no longer have an income, but can still afford some college education. None of us can work.

This is my plan of action: i want to study to become a CRNA, as there is a big shortage of nurses. This will allow me to get sponsored to work, and then i can get my green card and sponsor my mom back into the states. From what i have researched, i plan on becoming a LVN, as it only takes a year, and then i can start working. From there, i want to become a Rn by getting a ADN, so that i can start working for a higher salary. at the same time, i can work with an ADN while i study for a BSN (ill do an ADN to BSN program). With a BSN, i can attend a crna school and viola!

I think the path is good because it is the cheapest path, and ill also be able to work and earn some income (which we dont have right now) while i study to become more specialized. Any comments and feedback would be greatly appreciated! Tips are also welcome, anything to help me become a crna in a cheap way. thanks!
