Stuck in India during lockdown, could this time be used for Porting to Eb1c

Hello,

I hope you are doing well and are safe. Appreciate if you could help with some pointers on below:
I arrived in India in mid-march for my visa stamping dropbox. However on the day of landing, I found that my appointment is canceled. As Trump has suspended visas till end of 2020, I was wondering if I will be able to use this duration to become eligible for EB1 porting. I currently have an approved i140. Till now I am on the US payroll. Do I need to be on Indian payroll to be eligible for Eb1c porting? Kindly help.
