I think the question your trying to ask is:yes she is iv already supplied the extra documents while changing the status, copies of the marriage documents and translated copies is it fair to say if any one has experience being close to 6 months is it a possible chance that my visa would get approved
If the CO has asked for extra information 6months in, is your visa close to being approved?
The answer is who knows. Maybe, maybe not. They may require more time to review.
Some people submitted the requested information and still had to wait another 7 months.
So you'll have to be patient.
If you're lucky, it'll be approved soon but no one knows when.
