I want to apply for a UK visa - Stage 2 of global talent fast route. However, in the part of the form where they ask to disclose past visa denials, I have a past denial from South Africa from a visa extension where the reason was "Incorrect Section" and "Incomplete Medical Form" (missed only the address, but it was stamped).
The outcome came 6 months after the expiry date from my initial visa. The only way to appeal was with a letter of good cause, for which I have the application certificate. The outcome came 4 months later, when I had already left and could only pick it up in person.
Is it wise to disclose this in this section? It makes sense to me, specially because VFS is involved in both visas.
How bad this would this affect my overall visa application? Everything else is good, including signed contract, endorsement, HR letter, etc...
