H4 Drop Box Eligibility

Hi I am in US and my Spouse in India. I changed my Employer and got approved H1 B petition till
Dec 2021. I Have not travelled to India and I don’t have my New Visa stamped yet because I did not travelled to India after I changed my Employer. My Wife ( who never travelled to US so far ) had approved H4 Visa based on Previous Employer TCS and it got expired on Aug-2020.

My Question is, does my Spouse is eligible for H4-Visa Drop Box with my new Valid H1 B Petition Documents and other supporting Documents? Please help me out with your thoughts.
