Most of what I said here based on the outline is true for the bill as well with one important exception: the bill bars all legal immigrants from the path to citizenship except for H-2As and those in "essential critical infrastructure labor or services" https://twitter.com/David_J_Bier/status/1362141643760160769

There is a drafting error, but as it is actually written now, only A nonimmigrants (diplomats) are excluded, but that's clearly an error b/c the list after "other than" doesn't make sense. That means Dems will have to double down on this to remove legal immigrants from the bill

The fact is that many Hs, Ls, Es, and other nonimmigrants will meet the definition of "‘essential critical infrastructure labor or services" but many will not. It's both better than being totally left out and bizarre to exclude those following the law https://www.cisa.gov/publication/guidance-essential-critical-infrastructure-workforce

Nonetheless, this provision in combination with the recapture of unused green cards, increase in the EB cap, and other provisions mean the backlog will improve significantly for all employment-based applicants.
