Hello Isabela,

So here's what I know. If they're an EB-2 or EB-3 green card holder, changing jobs or roles can impact their status since their green card is tied to the job they were offered. To avoid issues, they'll have to wait at least 6 months after getting their green card before switching. They'll also need to ensure the new role is similar to their original one.

They should also try to consult with an immigration attorney before making any changes just so they stay compliant. Best of luck.
