My guess this will allow 3 million a year come across the Mexican border. My bet is only 5% are vaccinated for Covid. This will make them healthier than stupid Americans who got jabbed. They are younger, this is the incoming replacement population.
Most are from Central America. Then South America. Then the rest of the world.
If you asked me, I would say that the “refugee” petitions should not be accepted from illegal border crossers. We will never have the capacity to evaluate them, and they are increasing exponentially. In fact, this will ensure that immigrants more deserving than the line jumpers are excluded.
