What you have to realize is ICE has what amounts to a no constitution zone anywhere within a hundred miles of an international border, including coastlines; they need no reason to stop you in here. This affects all of FL, MS, Louisiana, and NJ, petty much all of New England, most of CA, OR, and WA, NY (all of NYC), MI, WI, PA, large chunks of every other border state north and south.. basically about half the land mass and 9/10's the population.
I suppose Colorado is still okay to visit.
