I signed up for a Citi credit card and in the application added my spouse as an authorized user so she could use it while I am away and we could meet the spend requirements (it's a mileage card).
If she's just an authorized user on the card, does that mean she is no longer eligible to sign up for the same credit card in her own name? People normally sign up for these one for each spouse to maximize mileage bonuses, and I'm curious if I have already ruined that by adding her as an authorized user.
