Truth be told, I am so happy I decided to keep my marriage a secret from my ex (we have kids together) because I know he would have done the same exact thing!! Unfortunately, I think it may get the VO thinking because of this, and so an interview...
HOWEVER, I am sure your relation is genuine and the interview will go very well. Do you have any "red flags"? We had some what would be considered "red flags" by CIC, but my hubby was given visa same day of interview. Prepare well. Prepare proof of ongoing relationship...Best of luck. Pls. Keep us updated...!
