“Can’t stop migrant flow? Hope you like tariffs!”
Go for the remittances Too!

Congress has to do that. As best as my research has indicated, there is zero authority in the executive branch to tax remittances, unfortunately.

Invoke a tariff on the remittances, the Mexican source of GDP !
That will get the Mexican government attention !
Mexico depends on remittances to keep the peso stabile.
