The American male is legal in United States, born in Ohio. The Cnadian female is legally allowed to visit United States for 180 days per year but wants to get married while in the United States.
I'm not sure what your question is, but it sounds like you need to speak with an immigration attorney. No law forbids a Canadian national and citizen from marrying an American in the U.S., but your question is probably more geared towarded having the Canadian remain in the U.S. after she is married. That question is one of immigration law.
