What about the much-simpler solution of not letting them in in the first place?
If we agreed that the U.S. has no choice but to let in droves of Third-World migrants (and I most certainly do not!), then, of course, the policies and measures might be worthy of consideration
But I don't accept your (as-yet justified) premise that the U.S. has no choice but to allow itself to be inundated with peoples who could be "integrated" only using such measures!

You cannot bypass the fact that your entire argument for why they shouldn't be let in is rooted in your initial claim that they are genetically incapable of meeting the standards I proposed.
If, as you claimed earlier, their intelligence is fixed and their 'nature' is the problem, then your exclusion policy is just a downstream effect of your biological essentialism.
First, you should acknowledge the inaccuracy of your biological claims before we move further to any sensible discussion
So, let's stop jumping around:
If you stand by them, then the debate is about biology, not immigration policy, and you need to provide evidence that holds up to scrutiny.
Or,
Address this first before we mvoe on
