VisaJourney.com is a good resource...I used it myself.
My wife is Indonesian but was in the U.S. on a student visa when we met. After we married (in Vegas), I did the paperwork to convert her status from Student to Spouse. She had a green card within a year, and after three years of marriage was able to apply for citizenship. Two years later, she stood in a USCIS office and swore her oath. She's 'Merican now.
So it is possible. It took us five years, a lot of paperwork, and several thousand dollars. We did not get an attorney involved, but depending on your wife's past it may be necessary for you.
Good luck.
