by the Trump admin in 2019, the asylum process crafted under the Immigration Act of 1990 (signed by GH Bush) was grinded to a halt.
According to DHS, "Aliens whose claims are found meritorious by an immigration judge will be allowed to remain in the U.S. Those determined to be without valid claims will be removed from the U.S. to their country of nationality or citizenship."[13] By June 2019, over 12,000 migrants had been returned to Mexico under the policy.[7] By September 2019, 47,000 people had been returned;[14] and 57,000 by December 2019.[15] Human Rights First found that at least 636 of those returned were victims of violent crimes in Mexico, including kidnapping, rape, torture, and assault.[15] As of September 2019, fewer than 10,000 migrants in the program had their cases reviewed: 11 had been granted asylum; 5,085 cases were denied; and 4,471 cases were dismissed without being evaluated, often on procedural grounds. The asylum admission rate for the program, 0.1%, is dramatically lower than the 20% among other arriving immigrants.
With organizations challenging the legitimacy of MPP it was often on/off going through court battles and most likely to lose. This is why a ratified law and not executive policy is needed to fix the mess that BOTH sides have ignored for years.
