sent it as recorded signed-for mail... got a confirmation letter from the Home Office today.. just waiting now for the letter re biometrics...
seems like the post office tracking system hasn't been updated to state that my mail reached the home office... got me worried there as it has been 7 working days from the time i sent it...
by the way, the question was suppose to be hypothetical.. lol.. how'd you guess i was describing my case? genius! LOL... my fiance visa expires on 1st of March so i'm not overstaying or anything... thanks guys!
