I thought they’re not allowing anybody to ask for documentation of whether a person is in the country legally. If so, then when would a machine-readable passport or visa ever be read? How would anybody ever be caught overstaying?
We are still checking passports and visas at our airports, ports, and at the border. You just don’t walk off a plane and go straight into the US. You also don’t leave without doing the same thing, i.e., go thru passport control. Your passport and visa are scanned.
