Hi cocorice, as I mentioned in my first post there is no priority visa service available for you in the Philippines.
The current priority service on offer is not applicable to any visa leading to settlement routes.
I did understand that was your major concern, that's why I gave the comment.
But I am also concerned to be sure you DO understand what you're getting into.
Please do forgive me if I'm wrong, but have you considered the need to meet English Language test? Maybe your existing pass certificate has expired.
Have you considered the need to arrange a TB screening test in the manila centre?
I am not in a position to guide you on your current immigration status as I do not know it.
I can however say that normally any overstay in UK when you voluntarily leave is not used against you in a subsequent settlement leading visa.
It really does depend on whether UKBA consider you have used deception and/or did not leave UK voluntarily and using your own funds.
Also whether UKBA believed there had been an attempt to circumvent immigration rules.
