Do you know if US Bank does a hard pull for recons?
Sometimes they do. They should be able to tell you if second HP is needed.
What was your score when you were approved?
Congrats. You got twice the SL I did. I was approved in late January this year for 1.5k with a 715 TU and when i called for recon they HP me again and said nope, try again in 6 months, too many inq. It is my lowest limit card but im sticking with it due to the cash back.
