Do we know that to be true? Because DHS on Tuesday said their visas were being canceled. Why would they talk about canceling visas if they were invalid.They overstayed their tourist visa, and if that can be proven by DHS, then they are here illegally and that is the due process they should be afforded, and then they can be deported.
While I have some sympathy if they are being target for the "sins of the father," if they really had overstayed their visas I don't have a major issue with deporting them. But there is no reason to assume they were on the same visa as the father.
