Canada Visa form query

Hi,

I am planning to take Canada visa. I am applying from USA and I am on H4. My visa H4 visa expired and I-94 is valid till November 2023. I will be applying for H4 and H4 EAD along with H1B in sometime. Now while applying for Canada visa, they ask for current country (which is USA) , From date and To date.

Is To date needs to be added till Visa Date / I-94 expiration date / future date or any other date (as I will be applying for extension)

Thanks in advance.
