I traveled to South Africa back in 2018 and was involved in a car accident. Because I was receiving treatment there decided to apply for a visa extension which takes up to 2 months. I was denied and had to leave the country to which I received the ban upon exiting. I was told to submit an appeal at the embassy in my home country after I explained my situation why I had overstayed, to which I later realized needed documents I needed from the hospital I was being treated at. Unfortunately I had no one to collect said documents nor did I have the means to hire a lawyer at the time. That was all back in 2018. My ban is expiring this coming August.
What I want to know is, can this affect my UK visa application even a job sponsorship?
I'm from Malawi by the way.
