Hello,
If your wife does not have an income to provide her own night, rejection comes. (They want an average of around 1400 net income.)
If your spouse is staying with his parents, he does not have his own income and if his family provides his night from Arbeitsamt, the rejection comes again.
In addition, if the square meter of the house to be experienced is considered insufficient, again, unfortunately, rejection comes.
In fact, German or Turkish citizen, no matter where I will stay on in the am pretty important from two points of Turkey and how to provide livelihood?
You can improve these conditions and try again.
