ICE is rounding up migrants. However, they are not being arrested and deported for solely being a migrant.

Let's define what the word "migrant" means. A migrant is simply a person moving from place to place (country, money, environment, etc.). That's it. Nothing to do with legal status. Plenty of people are migrants that are in the country legally and are not criminals.

These terms are distinctive and important. Bad actors try to mish mash the terms to get us to use them interchangeably for evil intentions. It's decades in the making so the masses wouldn't know the difference and the perpetuators would wield these labels as a weapon against population.

It's been rather effective up until several years ago. I think we all know why that is.

Quick Clarification:
All Illegal Aliens are Criminals.
They by their act of entering our Nation illegally violated US Immigration Laws which is a Crime.
Many of them Voted Illegally in our US Elections which also is a Crime.
Many of them are engaging in Financial Fraud which is also a Crime.

That said, IMO...
ICE is rounding up VIOLENT CRIMINALS as a First Phase that by their very evil nature pose immediate danger and safety hazard to the American Public.

I reckon that the Second Phase will be rounding up Financial Criminals.
Perhaps the Third Phase will be rounding up those who Illegally Voted,
or maybe these 2 Phases simultaneously.

Then as a Final Phase, NESARA-GESARA-TRUMPSARA will incentivize those who simply came here illegally for work opportunity to GO HOME, self-deport in a mass exodus, as they will not receive any benefit except if they return to their home country.

Those Phases completed would probably leave few if any Illegals to detain & deport, hopefull
