If you are married, you cannot file fiance visa.You need to file I-130 and or K3 visa. If not, you must file fiance visa for her to come to the US. Once in the US, you must marry her within 90 days. Then she files I-485 to adjust her status to permanent resident. She will receive employment authorization in about 2-3 months after the filing.
