Current status is H4. But have valid H1b which is expiring in March 8th 2018

Hi,

My name is Vasudha. I was working in H1B in A company till Nov 2016. I took a break for my new born baby and converted to H4 status. I have started to search for jobs now. I have few questions regarding my H1B:

  1. Will my H1B still be valid. My I94 expires in March 2018.

  2. What if I get an offer? Will the company put for H1B extension since I have not worked from Nov 2016. I will still have 1 year left. Is that right?

  3. Should I travel to India for stamping if I get an offer after my I94 expires?

Thanks in advance
