Similarly enforcing 8 USC 1324 against all who aid, harbor or employ illegal immigrants will end illegal immigration and force those who are here to leave with those outcomes beginning in literally one day.
Within a very short period of time -- weeks to months -- there will be no illegal immigration or problem with it other than those who come with the express intent to break the law and those people we can easily deal with since by definition that's all who will be left.
Why? Because nobody is going to do 10 years in federal prison touage their "feelings" about illegal immigrants or toist them. Not one farmer will spend 10 years in the pokey so he can have cheaper labor, nor will one roofing company. They'll either hire Americans or legal immigrants because the alternative is that they do 10 years in the Graybar Motel and their business is destroyed. Likewise every US based entity or person of a foreign entity who is here in the US will stop aiding these people with clothing, food and shelter because none of them are going to willing do 10 years in the slammer either, nor will they risk that becoming a life sentence if they choose poorly on who they help and that person kills an American.
These penalties, by the way, have been on the books since the 1950s and as such enforcement is all that is required to absolutely resolve the illegal immigration problem and remove every person who is here illegally as virtually all will, if this occurs, leave on their own.
Doing this would also instantly resolve the housing cost problem because it will put five years worth of housing supply into the market immediately.
