Lana,
Thank you for the reply. The reason for such a rush is that I am on H1B but I need to change to H4 status due to company's financial situation. I heard that it usually takes three months or even longer to get the approval notice of changing status to H4. And during these few months, I may find a new job and apply to H1B again.
So some confusion rose. If in H4 pending, I can’t work until the new H1B get approved, right?
If the answer to the above question is correct, then I will use H1B premium processing in order to be able to work earlier. But in this situation the H4 may get approved later than the new H1B, will I become a H4 holder again? Is there any way to make sure the new H1B take precedence than the H4?
Thank you so much for answering my questions.
