I was in a similar situation but it wasn't a problem I applied for a visitor visa and never mentioned my wife . Renewed the visa from 6months to 2 years visit visa Later applied for marriage visitor visa which valids for 6 months then back to visit visa 5 years before I changed it to settlement visa...

I made my application April the 24th 2017 still awaiting decision Married To British with a British Daughter does anyone made an application within same time the waiting is frustrating

Yea I did they said it's awaiting decision I'm so tired of waiting it's putting ma life on hold

I have just checked mine the date has been removed but still awaiting decision. I applied April 24th 6 months gone already
