Congratulations on ur PER and in advance for the wedding. Your situation is sthg dt needs carefulness n planning.
With d rate AVO is going, they MAY likely call u for MR before ur wedding and if possible, ur PPR . Now that is still a hypothetical situation. If I am the one, I will consider doing court wedding soonest (at least that one is devoid of huge expenses and all)and inform AVO of the update so that your wife's processing can start. Heads or tail, if u do the wedding before the MR and if you do the wedding after the MR and inform them, ur process will be delayed a little bit. HOWEVER, its the best option available to u cos if you DONT inform AVO of the wedding and your change of bachelor status before your visa is issued, it will be near impossible to bring her to Canada as they will inform u that in section xyz, you did not fulfill one thing one thing because u failed to
Inform AVO of ur change in status during the processing of ur visa. You can chk our sister forums either naija applicants or fsw 2013 forum, there was a sad case like dt and the forumite was denied flatly whenn the spouse now immigrated n then decided to sponsor him.
So, its your choice now, pls make haste n take a decision while they re still processing your application. Cheers.
