Coridr reads a file the way an experienced reviewer would, and it does not get tired at 2am in August. It reads the whole file and looks for the things that get an application sent back.
Across every document, from the passport to the transcript to the invitation letter, including the spellings that shift from one to the next.
So nothing has expired or sits outside the range the route allows.
Whether they cover the full period, whether the balances add up, whether a large deposit lands with no history behind it.
Measured against what the route asks for, whether that is study maintenance or the means and the reason to return from a visit.
A letter of intent and transcripts for a study file, an employer or invitation letter and travel history for a visit or business trip.
When a file shows ready, it means the documents meet the requirements for the route. It does not mean the application is compliant or that the visa is approved. That call belongs to the officer, and no tool can make it for them.
Coridr checks documents. It won't rule on whether a document is legitimate, and it does not run registry checks against WAEC or any institution. That judgment stays with a trained reviewer. Anyone selling you a scan that promises to catch a forgery is selling you liability. We would rather tell you plainly where the line is, so you know exactly what you are relying on and what stays your judgment.
