Yes - exactly - and we have existing, court-cleared federal felonies prohibiting employing, abetting, housing, and transporting Illegal-Aliens. When those laws were enforced, we didn't even need a "wall" to keep them out.
In 2016, Trump promised to enforce those laws - and he needed nothing from Congress or the Courts to do it. That's why we voted for that "NYC Values" degenerate weirdo - because we thought he wanted to be the "hero" who saved America.
Sadly, we found out that Trump cared more about the interests of Jared's cult - who imported all those 3rd Worlders - than about being hailed as the savior of the USA.
