Whether I can pursue a green card through a company other than my current employer
Hello, my current employer won’t sponsor me — I’d like to know if it’s fine to change jobs to a different company under my current status, and pursue the green card through sponsorship from the new company, rather than my current employer sponsoring me.
You don’t need to change jobs — the green card process can proceed as long as either your current employer or a different one is willing to sponsor you. It can even be done simultaneously, meaning you don’t necessarily need to switch jobs.
