"Entering the United States without being inspected and admitted, i.e., illegal entry, is a misdemeanor or can be a felony, depending on the circumstances. 8 U.S.C. § 1325."
Being in the US without legal status does not require illegal entry, because legal entry does not automatically come with permanent status. Being undocumented is a civil/administrative matter, not a crime, though some of the undocumented may also have committed crimes.
Weird take when ICE are infamous for staking out courthouses and scooping up people working their way through applications and appeals.
Further, undocumented aliens in the US are guilty of civil infractions not criminal felonies .. these are a seperate issue altogether.

Perhaps consider getting a clue about this rather than repeating falsehoods.
