I applied for the Olympics promo, and received the white card instead with a $10K limit. Unfortunately I didn't notice until much later (rookie mistake). In my last AOR I tried for the Club Carlson card but was denied - too many recent inquiries. Now I get a letter saying the limit on my white card has been increased to $15K.

What are my options here? I have no use for the white card, but I'd still like to get the Club Carlson card. Will US Bank transfer the credit line with a phone call and give the sign-up bonus? Any other good options?
