US Immigration from Turkey

Hi everyone, our NOA2 approval is estimated to be any day now and we wanted to know if its possible to transfer our case to Mexico. We are living in Mexico City currently (I'm American, my fiancee is Russian). We aren't residents, but wanted to know the chances of getting the case transferred from the default location of Warsaw, Poland for Russian Citizens and what should we say the reasoning for the transfer request. (I was going to initially say the cost of flights, obtaining a Schengen visa, and travel time versus just going into our local Mexican US Embassy location).

Thank you

My wife's mother is being taken care of my wife while she is in Turkey.

My question is after my wife enters the US with her visa can she leave 10 days later without any problems and stay another 5 month in Turkey to take care of her mother ?

Would there be any problems because she entered and exited too quickly ? Or is that her legal right to be able to leave for 6 months ?

We are waiting for our embassy interview on April 11th, in Turkey;

1. How long is the visa valid for ?
2. What happens if my wife doesn't enter the US within the visa validity date (for example within the 6 months) ?
3. Do we lose all chances of her coming to the US or can we re-apply for another visa at any time ?

I received the K1 instructions file more than a month ago. I've been trying to schedule interview since then but "No Appointment Available". I called the embassy few times, but the only thing they say is you need to check the website whenever you can, dates open randomly. Any idea when the appointments become available?

Hello. I am new to this and I am kind of confused to where I am able to start a topic. But I do have a question.. When I applied for the I-129F, I sent pictures of my fianc and I, and I also sent proof of the flights and hotels we stayed at. But with all the searching I did online, I saw that you also needed to send a "proof of intent to marry within 90 days of being in US", but we never did that. The lawyer who helped us never told us we needed it. Did you guys have to send something like that in with your forms other than pictures and proof that you met? I am getting worried we will get denied since we didn't sent that part, but the application itself should be proof we want to marry.. Also said to send date of marriage we want, but how could we send that if we don't even know when or if we would get approved?

What did you all submit with your I-129F application?
