Create not approved user

Hello,
I am creating an user that is not approved:
MembershipUser user = Membership.CreateUser(username, password, email, null, null, false, null, out status);
I need to define its profile ... should I authenticate the user to add the profile?
But if I do it the user will be loged on which I don't want because it is not approved.
What are the usual steps to create an user, define its profile but yet not being approved until later?
Thanks,
Miguel
