It would depend on when you two were married. In general, an adjustment of status may be possible. You may find more information on this process here:

You need to file an I-130 petition for your wife, along with an I-485 "package". A possible problem is if you married within the first 90 days of her admission into the United States, which is considered visa fraud. You can find more information at the USCIS website (www.uscis.gov). Please let me know if you have further questions. Good luck!
