2016 H1b Visa not utilized (not stamped). Can I reinitiate again?

Hi All,

Need some inputs here.

My Wife’s H1b petition got selected from lottery when she was in maternity leave back in 2015.

After maternity leave (around Dec) she joined office and was looking for project. She didn’t find any onsite position until May 2016. Due to personal issues, she came to US in H4 dependent Visa. Afterwards, she resigned her job from the company. she didnt stamped her H1b visa. is there any chance we can reinitiate her H1B visa?

Her employer said, her H1b was not utilized within one yr, hence she need to re-apply again. Is there any other possibilities that we can consider?

Any input would be really appreciated.
