I'm on H1B status right now. I got approval last year and it got changed in October 2019. I planned for stamping but due COVID-19 I cancelled. My employer decided to close permanently byJune 30, 2020. I'll have 60 days grace period after that. I'm planning to pursue Master in different major at state university. My question is once I'll have I-20, do I have to go back for stamping?

Thank you!
