What is FinCEN?

Well MoneyGram and Western Union are about to find out. But they know anyways.

"FinCEN, the criminal enforcement agency run by Treasury, may be the most powerful of Federal agency because of its control of the banking system."- Craig Fuller Founder FreightWaves 11-29-25

"Funds derived from unlawful employment "- #FinCEN
On November 28 2025, FinCEN issued an Alert titled “Cross-Border Funds Transfers Involving Illegal Aliens”.

The Alert highlights the risk of non-U.S. persons (“illegal aliens”) in the U.S. using cross-border funds transfers and remittances to move illicitly obtained funds.

The question?
How does money transfer companies enforce the collection of documentation from an illegal immigrant that proves they are here legally?
