B-1 Visa

Many have asked this question before, but since rules and situations are always different, so here I go - I'm on H1B with an approved I-140.

A layoff recently impacted me - my last day on payroll is 10th Feb 2024. I will also receive a severance (lumpsum) within 75 days of Feb 10th. My questions are -

1) Given the market, it may take more than April 10th to finalize an offer and start the H1B transfer. What are the options ( if any ) to extend my stay beyond April 10th?

2) Many suggest applying for B1/B2 (I'm single, have no spouse to move to H4, etc), but I also hear if it's rejected then the time of my stay after April 10th will be an illegal presence, is that true?

3) Say I receive the severance lump sum on March 15th -- are the days from Feb 10th until March 15th counted on company payroll?

I have a valid B-1 visa and have traveled to the US recently in April 2023. Now my H1B petition has been approved, and I am eligible for Dropbox. My employer is telling me that if my case does not get approved in Dropbox, he is asking me to travel on B1 and then get the status converted to H1B. In my I-129, it was mentioned as a change of status, as my I-94 was valid when my H1B was approved. I wanted to know if there will be any issues with coming to the US on B1 and changing the status if they call me for an interview in Dropbox. Also, I want to know if it is possible to switch employers with an approved H1B petition before getting my visa stamped. If I change the employer, will it have any issues?

My son-in-law was interviewed at the US Consulate in Frankfurt in May 2023 for a marriage-based immigrant visa. They have requested his CV with traveling details for further processing. His case has been in Administrative processing for well over 90 days. I have two questions:

1. Is anything can be done to expedite the process?

2. He has traveled to the US on a B1/B2 visa four times prior to his interview from Germany. Is there any problem with him traveling to the USA to visit his wife while his case is in Administrative processing?
