Ok first let me update you about my case:
Remember my wife passport issue, that is now definitely fixed, I applied for a temporary pasport for her and my second son just to make sure, I have them before the medicals and the interview, and I also applied for normal passport just to see if hers will come back rectified!
So now I have received all passport with the right spelling

My second problem is on my both sons BC.
When I applied for their full birth C like this:
My first son BC is perfect all his moms details shows and mine except my city of birth is mis spelled!
The second one the same story with my city of birth mis spelled too, and on my name they typed a T instead of I .
I tried to convince the home affairs to sign me an affidavit they refused.
They said I must just for few month for a rectification.
But I'm planning to write my own sworn affidavit and get legalised at the police station, not that I doubted simon's knowlegde, but I was just trying to get as much option as possible if there is

So now this is my last heck on my application.
Simon ensured me tthat is not a problem, but I m still panicking, since its one lifes time chance !
What do you say mom?
