When I moved to the USA in 1997 to attend graduate school I had 15 years of credit history in Canada, but the US credit card companies refused to count this. Thus, I had to start from scratch in the US.
Based on my experience, it is more likely that your fiance will have difficulty establishing American credit status. However, since 9/11 and the establishment of the US Patriot Act, etc. I would think it's highly likely the US and Canadian credit card companies and governments are exchanging this kind of information (along with LOTS of other information that use to be strictly personal.) I doubt her credit rating would taint your credit rating, however, even if you got a joint account. I wouldn't sweat this.
Hope this helps.
