If my I140 is approved, do I need to keep H1B status in order for I140 to be effective? For example, if I change my status to H4, does all benefits of I140 (PD, work authorization of spouse) still apply? Can I submit 485 if USCIS has processed my PD?If not, can I get the benefits back once I get my H1B status back? 配偶已经是h1b了,因为异地,现在犹豫要不要放弃工作,放弃自己的h1b。帮人问的,谢谢!
