It depends. If you are a U.S. Citizen, then you can petition her and she can file for adjustment of status. As the wife of a U.S. Citizen, she is eligible for an immediate visa. This means that she does not have to rely upon an employer's petition at this point.
The process of obtaining conditional and later permanent resident status through marriage can get complicated. Your family should seek an appointment with an experienced immigration attorney for further assistance with the petition process.
The above is general information and does not create an attorney-client relationship.
If you are a US citizen, married to a foreign national who is in the US on a non-immigrant visa, you should apply for her permanent resident status.
The most favored category under US immigration law is immediate relatives of US citizens, which your wife appears to be. Adjustment of status may be available and relatively straightforward. Contact an immigration attorney right away.
