Don't get me wrong ... I admire you and your missus for the tremendous sacrifices you've made [jointly] over many years. But wouldn't you agree that the fault lies principally with the 'Professional Standards Bodies' HERE in the UK? After all, it's these blinkered bureaucrats who are setting unrealistic targets for already adequately-qualified non-Europeans entering this country as the lawfully-wedded spouses of British nationals (or whatever) ... solely to protect the interests of their OWN graduates - WHO, if truth be told, are in many instances a great deal LESS well-trained in their chosen disciplines!
And, until some degree of parity is reached (which, sadly, seems unlikely to happen!) this grossly unfair practice will continue to prevail.
