Being here illegally is a crime, a misdemeanor. If you have been deported previously and return, it is a felony punishable by up to five years in prison. It is illegal to work here for an illegal or for an employer to hire him. Illegal aliens commit other crimes like identity theft, creating false SSNs, etc.
You have described the orderly immigration environment most of us hoped we were living in. But along with rampant and significant election corruption, the enforcement of immigration laws has been corrupted.
My comment above suggests the fact that many "illegals" were transported via Executive Branch directives and provided with settlement resources changes the setting. - i.e., the choice as stated to include amnesty misses the point.
IMO it would be far more effective to just to ask whether the immigration laws you set out ought to enforced.
In that regard, I fully expect the anti-MAGA Biden/Obama Admin (bent on "remaking America") will attempt to bestow with his final act a preemptive pardon on all who may be in the U.S. on his last day in office.
