140已經批準,在等排期,馬上要被lay off,能用non paid leave保持身份嗎?
-Technically, when you are laid off, your H1 status is invalid, but if you can find a job in one to two months, your H1 transfer may be approved with I-94. If you find a job too late, your H1 transfer still will be approved, but the approval notice will have no I-94 and thus, you need to go to China to get the H1 visa to come back unless your current I-94 expires for > 180 days.
會不會影響之後H1b transfer (如果找到新工作的話)和H1b/H4簽證申請?
-You may change your H1 to H4 now if you want to.
如果轉之後的行業和原來的不同,還能relink PD嗎?
-Yes, you can use this I-140 PD as your future I-140 PD.
