I thin the application may be forwarded by New Delhi to Chennai or it may be returned to You as wrongly send. Otherwise they will register you as north region. So i don't worry you application will be back or get registration. But any way for conformation and suggestion post your query at e-sahaayataa available at www.icai.org under students option under Articleship catogery. They will suggest you and help you what action has to be taken by you.
