H4 visa stamping while Primary applicant still in US with expired visa stamp but approved extension till 2020

[visitor_ma]

Hi All,

I will be traveling to India without my spouse and I will have to go for H4 visa stamping as the last visa expired in 2016 and since then we haven't gone out of USA.

While filing an application for an appointment in Petitioner section what start date should I put? 

My spouse (primary applicant) is working with the same employer since 2014, between 2014 and now his visa was extended more than once. His latest I-797A has a Start Date as Nov 2017, Expiration Date is Nov 2020. 

He isn't traveling to India without me. 

My query is what should I give as Start Date since he is already working in the US with the same employer since 2014. Should it be the Nov 2017 as per the latest I-797A or should it be 2014 when he actually started working for that employer?

Thanks in anticipation of getting a response.

You are applying on the basis of his latest H1 Petition approval which started November, 2017.
