Losing your H-1B job immediately ends your work authorization, but you are not immediately out of status. The U.S. government allows a one-time discretionary grace period of up to 60 days, giving you time to explore your next steps. If you do not take action within this window such as transferring to a new employer, changing status, or departing you may fall out of status and begin accruing unlawful presence, which can impact future immigration benefits.
