If a Canadian Citizen visits the United States and gets married will she be deported?

I'm no immigration lawyer, but I'm pretty sure that Canadian citizens can visit the United States all they want, regardless of marital status. (After much hunting, I found it at http://www.cbp.gov/xp/cgov/travel/id_visa/req_canada_mexico.xml Sheesh! What a mess of a web site.) If genuinely marry (i.e. not for a fradulent purpose, like beating immigration laws) someone who is a legal resident of the United States, that can be an avenue to permanent residency, if you so desire. Your citizenship doesn't change just because you get married.
