I was approved for a WaMu Plat CC on 8-6-07. My dw will be an au. Maybe in a few months after her scores get better, I will try to have her apply for a joint. Congradulations by the way. WaMu has been our bank since 2003.
WAMU doesn't do joint CCs. However, they don't charge an annual fee, so it pays to go ahead and try for an individual WAMU CC once the AU TL is reporting. For the next few months, on 2 of the 3 CRAs, you'll still benefit from the AU TL. WAMU tends to pull TU, and EX is the one rumored to be dropping AUs from scoring in September.
WAMU gave me a $2K CL. DW got hers in the mail today. She got a $4K CL. Puts us up to $32K in total CC CL.
