As I recall, Donald said he immediately deport at illegal aliens who have committed crime and then would announce the next step.
I suspect he has already ordered that all immigration laws on the books be enforced with gusto.
Offer them an option. If you are illegal and stay in this country, only family members born after 2009 can vote in elections. If you do not accept this, you must return to your country of origin.
If they whine about it, you know it isn’t about immigration.
