My fiancee is married what can i do?

From the way you asked the question, it sounds like your issue has immigration overtones. If your fiancée has had a marriage ceremony anywhere in the world, you must disclose that information to USCIS and she must be divorced before she can enter the country on a fiancée Visa. Do not mislead or deceive the service on this issue because as her sponsor, you are swearing under penalty of perjury that the facts contained in the I-129 are true. If you mislead the service, that is a felony. So, I agree with the former answer, you must first be divorced before you can get married in the USA
