USA Citizen Marrying Iranian Citizen in Ankara, Turkey

Hi I am a USA citizen and live in the USA.
My fiance is an Iranian Citizen that lives in Iran.
We have Plans to fly to turkey in a few weeks to get married in ANKARA, Turkey.

I have a few questions...
On arrival I have an appointment with the USA Embassy to get my paper work of "free to marry".
My Fiance will be going to the Iranian Embassy in Ankara and also getting a document of "Free to marry".

After we get our documents, we will take them to the Consular Department of the Turkish Ministry of Foreign Affairs (MFA) to get authentication of the papers.

We will then go to a marriage bureau for everything else.

Is there anything important that I am missing?

This is the documentation I am bringing with me to Turkey:
IS THERE ANYTHING I AM MISSING????
-USA Passport (Also Copy of this converted to turkish)
-USA Birth Certificate (Also a Copy of this Converted to Turkish)
-Background check of USA Citizen
-at least 12 "2x2" inch photographs
-2 letter sized envelopes


Anything I am missing?

THANK YOU SO MUCH!
