My passport is stamped from 5/11/2020 to 30/09/2022 for student visa. I have deferred to next fall 2021 and I haven't received my new LOA while my passport stamped. I received my new LOA after stamping of my passport. It's more than 150 days for next intake which I have opted. Giving my new LOA at POE is enough Or need to start the process again?
