What “the books” say is that H1B is a “nonimmigrant” visa for people “temporarily” in the U.S. It’s right there in 8 USC 1101(a)(15)(H).
“Adjustment of status” is an option at the discretion of the administration (8 USC 1255(a)):
> The status of an alien who was inspected and admitted or paroled into the United States … may be adjusted by the Attorney General, in his discretion and under such regulations as he may prescribe, to that of an alien lawfully admitted for permanent residence
Note the “may” and the “in his discretion.” Basically, if the government really likes you, it can change your status. But that doesn’t change the primary purpose of the H1 visa from a temporary worker program into a permanent residency program.
> Note the “may” and the “in his discretion.” Basically, if the government really likes you, it can change your status. But that doesn’t change the primary purpose of the H1 visa from a temporary worker program into a permanent residency program.
Where this falls apart is that the K-1 Fiance visa is also a non-immigrant visa, that through Adjustment of Statuses (based on your demonstration of a genuine and sincere relationship) becomes a green card pathway. All "may", "at their discretion", on a non-immigrant visa.
But then what is the purpose of the K-1 visa? To allow you a US citizen then perhaps, maybe, one day, be allowed to stay in the same country as your spouse? At the government's discretion, of course?
One of two things happened here:
1. You just quoted 8 USC 1255(a) because it's at the top of the USCIS memo without understanding it; or
2. This is just the most ChatGPT comment.
I say this because you clearly don't understand this stuff. From reading your comment history, you're a Trump supporter [1] and you seem to have done the most MGA Thing of being told what your position is and then looking for a justification.
8 USC 1255(a) is a carve-out that basically gives the AG authority to let people adjust. It doesn't go the other way and say the AG can withhold permission to adjust. The entire section details the requirements to adjust, detailing admissibility requirements.
So how did we get from the AG can allow someone to adjust to the AG can override the entire section that details adjustment requirements?
Also, you don't understand what "nonimmigrant" means in relation to your H1B comment. Yes, H1B is a nonimmigrant visa. That just means they're not a lawful permanent resident ("LPR"). It doesn't mean they can't adjust status.
It's a bit like taking the description fo a woman as "non-pregnant" and taking that to mean they're not capable and/or not allowed to get pregnant.
A misrepresentation. 'Adjustment of status' is not 'if the government really likes you', it's a process that's available by rule. And the federal rulemaking process, as you are fully aware, involves publication in the federal register, solicitation and and collation of public comment, and republication of teh final rule, again, in the federal register.
Incidentally, we don't have an attorney general at present, only an acting one (Trump's former personal lawyer), and I question the standing of an unconfirmed federal officer to alter existing rules, never mind to bypass the federal rulemaking process entirely.
