I have a special tourist visa. I entered the country May 4th 2021.

When I applied for it, it was supposed to be valid until February 2022 (after 3 90 day extensions). Now I see they are only allowing me to extend until September 30th. The visa is nontransferable.

My biggest issue right now is I have just had my first dose of AZ vaccine on Friday July 9th. My next appointment for my second vaccine is not until October 1st.

Does anybody have any insight on whether or not I will be able to extend (even temporarily) just for enough time to get my second vaccine and then fly out of the country after that?

I do NOT want to risk an overstay.

I have spoken with the hospital and they said they don't even know what date they will be supplied with more vaccines yet to give the second dose so I have to go back in September to check if I can move my appointment a week sooner.

I have spoken to immigration and the intake officer giving information wasn't any help.
