As presented, that dude's story as makes little sense to anyone familiar with the immigration process. There is more to this story, I wish the reporter would just tell it.
If it surprises you, then you haven't paid attention to the blatantly unconstitutional actions of DHS in this administration. The purpose is terror and filling deportation quotas, not enforcing immigration law.
The guy from the article would have been deported by Biden's ICE too.
