Hey, thank you everybody for the help, I am going to send back my first page(declaration of health form) tonight, and I will fill out all the appendix's as soon as possible
Flybmicrew, I took literally everything with me. I was well prepared,but I write it to you one by one:
-pasport sized photos (6)
- full lenght business attire photo (1)
- passport copies (2)
- letter of reference (3)- they asked only one, but I wanted to be sure
- Highest education certificates (1 copy of my diploma)
The only thing what I needed to resend was the casual photos(2).
These stuff usually needed only when you go to the FI, but I wanted to be sure I will go there, and I did, you see positive thinking

Good luck for your OD, learn as much as you can before it, and prepare your stuff in time, and wear your nicest smile and you are definitely fly to Dubai

Any further question , pm me
