فقط جهت اطلاع بیشتر دوستان ایمیلیو که از سفارت در جواب سوالم در مورد مدرک زبان آلمانی برای همسر گرفتمو میزارم اینجا:

Please have a look at the homepage www.teheran.diplo.de where you can
find all necessary information regarding family reunion visas.
Please note that a proof German knowledge at A1 level depends on how
long you intend to stay in Germany.
In general, if you intend to stay in Germany longer then three years, a
proof that your wife knows German on A1- level is mandatory.
Nonetheless, please note that some authorities insist on a proof of
German knowledge even if the stay will be shorter then 3 years.
Therefore, please be aware that your wife might be asked for a proof of
German knowledge later on while her visa application is processed.
In any case, I would recommend to learn at least the basics in German to
be able to handle everyday life in Germany.
