ITIN:
Indivitual Taxpayer Identification Number
The IRS already KNOWS where 90% of these people are.
And Social Security knows whose number they are using, but won’t tell the person whose number they are using.
When Census question was not allowed by Roberts the plan B was immediately gather all fed databases to give an accurate audit of citizen/legal/illegal.
That can be combined with ITIN and social security info (legal and fraudulent) to help locate illegal for ICE disposal.
Is the will there? Better be with the advanced voter fraud in all urban rat controlled areas now. Deport and check/purge voter rolls.
