Sorry for writing in English.
I was looking around in this form when I came across your question.
I must told you do whatever you can but do not send your wife back to Lebanon to apply for
FZF or whatever at the German Embassy there.
Everyone here is speaking theoretically, no one has ever gone there and see what is like in practical.
I am speaking from my own experience.
I am in working Germany since 7 years, and married since two years from a Lebanese women. We started applying for
FZF since February last year.
First, they will tell you to come personally to apply for an appointment. You wife have to wait in lines for hours, and if she is lucky enough, she will get through and reach the gate on time. But, this is not everything, she should be too lucky that the authorized employee is actually there and is not absent due to a “personal reason”, otherwise she just has waited for nothing.
And when luck play her a favor, and she actually reaches the guy, he will take her telephone number and tell her, they will call her as soon as there is an appointment; which will never be. Do not bother calling the embassy from a Lebanese line, they will never pickup. Writing an Email is also useless.
So, after waiting for nothing for a couple of weeks, your wife has to go there again, and cycle restarts.
Do you now some offices are actually selling appointments for
FZF at the Embassy. Most of them are fake, but when you are desperate enough, you may try.
As I said, we started applying on Feb 2016, my wife get pregnant on Apr 2016, and even that did not help at all. My son is now almost 3 Months old, and my wife is still there.
And do let me start on the documents they ask for; most of them are non-sense and nerve racking. First,
A1 certificate, which my wife passed with flying colors; hopefully yours too. Then, they will ask you to submit a document showing your travel movement to/from Lebanon even If you did not visit Lebanon for the last 13 years. No one can acquire this document other than yourself, and do not try to apply for an “special” attorney at the Lebanese Embassy in Berlin. Believe me flying to Lebanon is much easier.
And guess what, this document IS ONLY VALID FOR 4 MONTHS!!!.
And if someone told you, do not rumble too much about the Syrian refugee problem. Do not listen. The whole embassy is full by Syrian!
Not to be too long, ask around, hire a lawyer, do whatever you can, because otherwise, you may never see your child until he is one year old.
May luck be on your side.
