I’d first say 5.7 is not a permanent wall or fencing. It is only a partial one. It is not a permanent wall, it only covers one part of the border. This is only a temporary fix of the issue, the permanent solution to DACA kids would be much more than the 5.7 billion.
A permanent one would be $25 billion, which is what was asked for last year, even the Democrat offer last year was $25 billion but had several things that was objectionable including chain migration and not ending the visa lottery, etc. $25 billion over 5 years or so, $5 billion a year, built into it, the citizenship for DACA recipients, but not their parents who broke the law, work on the time frame on when citizenship can be offered, but if money withdrawn from completion of the wall/fencing (in only areas where practical) then the path to citizenship also withdrawn. Work on the time frame/conditions on citizenship, I think about 10 years or so. That is long term though. I think hammering all those details will not come in a week, with all the competing factions.
I’m sure E-verify mandatory & Visa overstay tracking and apprehension the Republicans would love it, I don’t think the Democrats would propose that, but most likely won’t be dealt with during this short term thing.
