Julidzg in my experience in Argentina, last OD in the city of Cordoba was listed, the AD was the following day (I didn't get an invite though) but it wasn't listed. Next AD in Buenos Aires is listed but the ODs are not.
J_sal your casual pictures don't have to be in a studio, they should be in a casual background such as vacations for example. But of course with you alone and no cigarettes or drinks in had. Try to have new ones taken, maybe go for a walk with a friend and find a good location to take some snapshots (as Mmm007 said up there).
I think with casual pics they want to see your personality and if you still look presentable and good in an everyday basis. Hope this helps, good luck!
