That's really a moot point (permission)
Just how is Mexico going to be forced to pay for the wall?
Add a surcharge to money transfers to Mexico ? ...A lot of that money is earned by americans or legally here mexicans...so a percent of that wall is being paid for by Americans...
Take the money out of their foreign aid package...That's american taxpayer money...
Send the Mexican government an invoice? ...good luck with that
I'm all for Mexico paying for it, I just don't know of a way to make them pay for it..?
The wall is estimated at only $8 billion. Trump's track record on building is under budget and on time.
From Trump's web site
Mexico must pay for the wall and, until they do, the United States will, among other things: impound all remittance payments derived from illegal wages; increase fees on all temporary visas issued to Mexican CEOs and diplomats (and if necessary cancel them); increase fees on all border crossing cards - of which we issue about 1 million to Mexican nationals each year (a major source of visa overstays); increase fees on all NAFTA worker visas from Mexico (another major source of overstays); and increase fees at ports of entry to the United States from Mexico [Tariffs and foreign aid cuts are also options]. We will not be taken advantage of anymore.
