H4- Drop box eligibility

Hi ,

I had my h4 visa stamped in sep 2017 when i visited india-- It is valid till nov 2020

After coming back to US, My husband changed his employer and got this H1 approved and it is valid till Nov 2020.

I’m planning to visit India now, Will I be eligible for Dropbox? Or should i go for H4 Visa interview?

Thanks in advance
