There must be a reason to wait 10 days, just be patient, if I were you I'll call them after the second week, that way you can simply ask, but by you calling them will delay their process. Remember that you are not the only one on their files and they have a difficult task in their hands.
Have a 5 min brake, have a Kit Kat and chill out !!!
PS: send me a PM as I'm also Argentinian, work in EK and I know Favio
