回复：请高手指点：H1b申请上I485后不到180天丢了工作，用EAD能保住身份吗？如果满180天后被裁员呢？

You don't need anything including EAD to keep your status, as long as your I-485 is pending.

Your EAD may help you work legally without H-1 or work for non sponsor.

Your change employer within 180 days of I-485 submission may bring negative impact on your I-485 approval.
