都說４８５pending１８０天後被裁員就不怕了，究竟是什麽意思？
if your 140 is also approved after 180 days of 485 filing, you can switch your employer, but you have to find a similar position and stay employed in case there is RFE or local interview
如果是在用H1B簽證工作，被裁員後是不是必須用EAD趕快找另外的
類似工作？
you don't have to if your new employer could sponsor your h1 so you can transfer your h1.
如果一時找不到工作也沒有關係嗎？
it's not big deal if you stay home briefly if there is no RFE during that time.
還可以繼續等綠卡？
ideally you should find a similar position right away and file ac21----actually it's only a cover letter plus a new evl
是不是一定要申請上EAD，以防被裁員後無法工作而丟掉等待中的綠卡？
you don't have to apply ead unless your new employer doesn't sponsor any h1
