1. Will her credit score/history impact mine in any way?
2. Might I be denied an AU with a bad score/history?
3. Are any of the 4 issuers above better or worse re my concerns?
4. If Chase is involved in why her score is bad, would they refuse a card for her as an AU?
5. Anything I'm not thinking of here? (And no, I am not worried about her abusing the card.)
