It's been day 41 since biometrics or 39 days from the date the application is received. Me and the husband are actually thinking of thinking of doing a retrospective upgrade but whether it will be accepted is the problem. This is giving me a lot of anxiety :-(There is no hard-and-fast rule about it. Anecdotal evidence suggests from when they receive your application and supporting documents. But remember it's only a guide and not an undertaking that your case will be decided within a given timeframe.
