hi
 
no, the i864 will be for adjustment of status once you marry
that is a generalized letter, a multipurpose letter for different petitions
 
the only one you need for the k1 is the i134
 
 

We already received notification from the embassy. Finally

The exact same thing happened to us. We got a RFE saying that we had no evidence of having met in person, though we lived in the same country for 9 months and provided lots of evidence to prove it.
 
My suggestion would be to go through whatever they are asking more thoroughly and REALLY make sure you are spelling it out for them. 
 
It did slow us down somewhat. Your post is making me wonder if its something to do with Turkey these days, honestly. 

Sounds like that guy is a complete and douchebag. Shame on him!

I was in the middle of a post and then @Dutchster posted precisely what I was going to say.  Protect your children OP.  Forget about her for now.  She made her bed and she can lie in it.  Even when being arrested, she was threatening you.  She says she hates you.  That's not love.  Do not listen to the weasel words and promises of change that I'm sure will now come once she realizes the deep sh*t she's in. 
 
God bless you for thinking of those children.  They need their dad and you standing up for them.... that's more important that you perhaps realize.  

I'm going to put in my two pennies with a similar situation except for the home country;

My mother started dating this friendly man mid 2006. All went well until we moved in with him, me, my mother and my younger sister. It was all sunshine and roses the first few months until he starts degrading my mother first. The friendly man was not so friendly anymore. Not long after he starts degrading, me being just sixteen but I rather had him degrading me than my mother. I had a difficult time with my parents being divorced and bullying at school and he became the home bully. What all started with yelling and degrading me, ended with physical abuse. I had to cover up bruises sometimes. But every time he did this, my mom defended him. No matter how hard he hit me or how loud he was yelling in my face, my mother chose his side and wanted to make their marriage work.  Feeling betrayed by my own mother; it really damaged our relationship. Eventually, at the age of 23 after he hit me incredibly hard and my mother still stood behind him, defending him, I packed a few bags and left the house to move in with my dad. Mom is still with him and I'm not sure how she can live under his controlling behavior but I know she isn't happy.

Moral of the story; Choose your kids and yourself, please. I was reading your story and I felt how your 11 year daughter must feel when your wife yells at her for no reason. Please don't damage your relationship with your children by choosing your wife who is capable of hurting them. Just because she doesn't put her hands on them doesn't mean she isn't abusive; Abuse is control, blatant disrespects and hurtful words. Don't settle for emotional abuse thinking it's ok because it's not physical.

Divorce. Don't sign any aos forms. Don't be alone with her. 

Hi friends,
 
My wife-to-be and I were waiting to receive our approval from the UCSIS. Just now I received a status update, saying that they are asking for additional evidence. They mailed us. It's not there yet, but whatever it is, even if we send them everything they want immediately, I have this feeling, they will let us wait very long for a response on that again. Anyone who had the same case can confirm it?
 
I don't know what the matter is. Our lawyer said our documents were the best ones she'd ever seen but now we're asked for additional evidence... Does anyone know how much this would delay our process?
Thanks in advance
 
Rico

Depends on the nature of the RFE I guess.
Usually they respond within 1-2 weeks of receiving your response, but in some rare instances it has taken over a month. It's a bit hard to tell. 

Exactly as above. Can be something simple like missed check on a box or signature, or asking for other materials. 

Your timeline lists your embassy as in Turkey but your flag says Germany
If you are a German Passport holder you can visit using your ETSA
 
Congratulations on the baby

You can certainly visit using your ESTA. I did this several times during the K1 process. 
 
The baby born to the USC mother will not change your visa processing. You will want to bring his/her birth certificate to your interview. The baby must also be accounted for as a dependent on your fiancées affidavit of support.
