I live in Canada about 10 miles North of the USA, so close enough.
The answer is… it depends. On location & the local culture.
If you move to a major port city, i.e. NYC, LA, Seattle etc then the chances of finding someone willing (or even wanting) to date a foreigner go way up because they're very diverse multicultural cities with immigrants from all over the world. (as it is here in the Vancouver area, BC, Canada.)
But if you move to the middle of nowhere small town USA or to the deep South, then you might have a harder time as people are more likely to be interested in their own very small cultured universe and the sameness that comes with all the people around them.
The USA is geographically HUGE and has over 350 Million people… chances are pretty good you'd be able to get a date there just fine - but it's likely to be easier in a major port city, IMO.
