What is the duration of notice period after sending the resignation letter?

I'm under an unlimited contract. I'm already 8 years in the company.

My visa and ID will expire on Jan 29, 2022. My labor card will expire on Dec 19, 2021.

On Nov 20, 2021, I already sent the notice thru email that I'm not seeking for renewal.

If that is so, when is my last day of work?

Please I need your advice.

Thank you
