Thanks a lot for your answer !!!!!!!
I wasn't thinking at the open work permit. I read in some internet article that the work has to be open and skill tipe 0 or A or B to count for the experience factor . They said , as an exemple,dentistry is a closed work and so it doesn't count and you have to try with a similar work if you can.
I really didn't find any other explication of that anywhere so I wanted to understand .
