Congratulations on your approvals!!! Did you choose "Spur" of the moment for the reason I am thinking? #COYS
Congrats on your approvals, SS!
Congratulations on your new cards. Both new cards sound solid and useful.
From my recent experience, if you're going to strategically apply for 2-3 cards, seems almost best to apply for them back to back, before the 1st card reports. I was recently declined on a prequal by Disco as my Cap1 recently reported. No harm no foul as it was a SP. I could be totally wrong, just an observation.
Sorry can't help with your questions. Good luck with US Bank approval...
Just got an email from U.S. Bank confirming my approval, and the card now shows up on my account online. 
Had a couple more questions if anyone happens to know the answers to:
1) From what I read online, you can call up U.S. Bank and get a CLI on your SL. Is that usually a SP? And is it worth doing in my case since I already got a $5K limit? Would be nice to have a card over $5k as it seems no banks want to break that boundary with me. 
2) When am I actually eligible for a CLI on the Capital One Walmart card? From what I've read on the forums, seems like it's 6 months. However, the Capital One website says your card only needs to be over 3 months old. https://www.capitalone.com/credit-cards/credit-line-increase/
