A flight from a Mexican airport to a U.S. airport is the only way for a person with a tourist visa to enter. For example, Guadalajara to Las Vegas... I know people who've done this. But by land, the restriction allows only American citizens and resident aliens.
You can cross with a tourist visa only if you take a flight from airport to airport
No, they cannot. Supposedly not until the 21st of this month. Best of luck!
