Hi all, I have received conflicting information.

My ED Visa is expiring in April. I was hoping to switch to Volunteer under my foundation. Under normal circumstances, I know I would need to exit the country. My school is saying I will not have to exit the country, but the foundation is saying I will. I know because of Covid, the rules are constantly changing it seems. I came in on TR Visa and switched ED Visa, in country. So is there any option for me to switch from ED to Volunteer without leaving? I couldn't find relevant info in the search that is from the last few months. Are there any options for me to not leave in April? ED to ED? ED to Volunteer? ED to Covid?

Thank you!
