Hello, good afternoon, I’m trying to apply for student visa to the Uk, but I’ll have to explain overstaying a visit visa by couple of weeks, my legal stay ought to be 6months due August 22, but couldn’t leave because of coronavirus and Nigeria AirPort being closed, the Nigeria airport was opened on the 5th, and I left as soon as I can September 12, I want to believe I has a valid reason for staying beyond the allocated time, and I left immediately as soon as I can. How can I explain this on my application, I have my plane tickets document also I’ve been buying since July and It being canceled to show I tried my best to leave.

How do I explain this on my visa application
