*Nat [hope you don't mind the *abbreviation] and Welcome! Having read about your predicament, I wholly agree with everything 'bornatbirth has just said. The fact that I happened to be RETIRED and living on a modest occupational pension had absolutely no bearing whatsoever on my wife's application ... which was approved well-within the three months' target set by the British Embassy.
So relax, ... secure in the knowledge that Spousal Visas are SELDOM - if EVER - refused! Good Luck, mate!
