I'm not sure if you are registering as a person or a company, but the company registration can take a little while. I registered (my company) on Aug 5th (Sat) and shortly received a request for documentation the same day. I submitted my documentation by fax on Aug 7th (Mon), and they confirmed receipt on Aug 8th (Tues). On Aug 11th (Fri) I received a phone call to confirm they could actually contact me, and shortly afterwards received an email letting me know I could continue. That same day I purchased the program, and by the next day (Sat, Aug 12), I had full access to iTunes Connect, etc. So it took exactly a week to process everything, although it seems they had no problems at all in processing my documents.
