If you lose your job, you usually have a 60-day grace period to find a new employer or change your immigration status.

Some work visas, like H-1B, allow for quick transfer if the new petition is filed before the 60 days end.

If you have a pending green card application, losing your job could affect it depending on your case type.

If you find a new job, your new employer must file a petition to transfer or sponsor your visa.
