You have to go to the local ins office for emergency AP, but you better have an emergency and proof of it, then depending on where you are, you can get it in a day or a week.
Service centers don't distinguis emergency ap and regular ap
Regarding your question, i don't know if you need to apply for regular ap, in order to qualify for emergency ap
but i would think that you don't need to apply for regular AP, because no one can foresee an emergency, so they probably should give you an emergency AP.
I myself would like to go with regular AP instead of emergency AP. Just a personal choice
