So would you please suggest how long ahead of time do we need to prepare and file the H1-B to H-4 transfer so that there is no gap between the H1-B and H-4.
The situation is a little bit awkward: she can't file the H-B to H4 transfer too early, because if her manager agrees her work remotely, she can remain in H1-B. On the other hand, if she needs to resign, there will only be 2 to 3 weeks before she left the company to file the transfer application, and we are not sure whether it is long enough to finish.
Is there any grace period between H1-B and H-4? What do we need to do with the above situation?
Many thanks!
