“Prevent illegals from having bank accounts and using wire transfer services “
Are you saying that the Mexican government’s motivation for letting their citizens come to America is that these immigrants send a lot of money back to Mexico?
You said earlier that this money-sending from America back to Mexico is Mexico’s largest source of hard cash.
A few years back it became widely known that remittances from illegals was Mexicos largest cash source. I can’t imagine thats changed since.
