We asked that too, they refused that as well! They said we can't do business with you until and unless you give us a proof of residency which could be the application number once we submit the inland application... I believe that the banks try to find a reason to not open your bank account! I do not know the reason, my bet is that they want to avoid you using their bank to evade taxes.
Plus, I don't get what the manager meant by that, since the added person has actually all the rights of the other person, and has to have a profile with the bank too, and we go in the same loop again!
