This isn’t right—it would be more accurate to say AOS relief from the GOP is not likely. Democrats nearly passed an amendment as part of the budget bill in 2021, which would have allowed AOS after a 2 year wait (exempt from EB caps). The bill was unfortunately blocked by the Parliamentarian: https://www.npr.org/2021/09/19/1038776731/in-a-blow-to-democ...
Democratic Senate leadership didn’t feel confident about the odds of overriding the Parliamentarian due to Sinema and Manchin, and that’s how that died.
If (a) Democrats regain the House, and (b) Democrats get a Senate majority w/o conservatives like Manchin — then it’s basically guaranteed that immigration reform will pass. Immigration reform is an extremely high priority for the Democratic Party.
2. Not happening. Nothing is getting through Congress anyway.
