The 'horse's mouth' gave you bad advice. A fiance visa requires that the sponsor be a permanent resident in the UK. That means a WP holder cannot sponsor. Had you actually gone through with your application, the consulate would have seen the problem and not issued the visa...
Unfortunately, I cannot say I'm totally surprised to hear that. After I really thought about it, they told me a couple of other things that turned out to be totally incorrect. . . . This is ultimately why we decided to just move our wedding up and go that route. They painted a pretty grim picture, and it sounds like they fed me a lot of BS on top of it! . . .I'm sorry I posted that now!

. . . .Nevermind, don't listen to me! (Or, apparently, the LA Consulate, either!)
I would want any advice in writing!
I asked, and they refused. Again, that's why we just went the route we did. . . .It seemed to be more of a "slam dunk."
Possible Sword, I hope its going well for you! Good luck!
