In December I traveled to Belgium on a tourist visa and left after 89 days (So within the correct amount of days), I was getting my paperwork done while I was there so I could stay, but the coronavirus, unfortunately, stopped that. I got accepted into Leuven... My fiance is Belgian, and frankly I want to be with her as soon as possible.
My question is this, I can't fly back to the EU until June 11th, But after that time is up, Is it possible once I get my student visa that I fly to the EU, enter Belgium as a tourist (my studies don't start until late September), then around September when I can activate my student visa, fly or travel to London or something so I'm out of the Schengen area, and then re-enter the Schengen area as a student when it's in September and I'm going to start studies soon? I understand that upon arrival I must tell the nearest town hall to confirm I am there, so that means I must do it twice in a short amount of time.
Is this possible? And if not what about something similar to this? I just want to be there, let me know thank you.
