What you're not understanding is the simple matter that the senate bill did little to address illegal immigration. The bill was drafted in the Schumer controlled senate to give the open border Dems / Marxists everything they wanted. There was so much left open to "discretion" on the part of Mayorkas and Biden that they could literally make up the rules as they went along.
What the Dems / Marxists don't want to acknowledge is that the lawless, open borders Biden politburo have reversed every single Trump policy that effectively managed illegal immigration. The Dems/ Marxists have completely abandoned adhering to existing immigration laws because they want illegals flooding the country. The Dems / Marxists were so anxious to import illegals that they included flying in some 320,000 that we know about.
You may be so gullible as to believe that layer upon layer of new laws would be adhered to by the open borders Dems/Marxists. Dont project that onto others. We have a history of lawlessness and corruption by the Biden politburo that demonstrates their intention to import a third-world voter class.
