As far as I know, someone entering Japan with student visa cannot take even a part time job unless he gets the so-called "a permission of activity outside the scope permitted". I have also been informed that one can obtain this permit right during his/her first arrival in Japan at the port of entry. I would like to know if someone here has experience applying for this permit. Can you please tell me where exactly at the airport I should visit to get this permit, is it at the same section as where I will get my resident card? Also, how long does this process take?
