Absolutely HP from Citi, and in my experience on Home Depot (and wife with Best Buy) it has been a double pull (HP on two CBs). If you enter the info on the Request A Credit Line Increase screen, then click Continue you come to a new window to verify the details. Right above the Submit button:
By submitting this form you authorize Citibank, N.A. to obtain your credit report.
Exact same language and process for Shell, Home Depot, Best Buy and NTB/Tire Kingdom for me. Citi's SP language always specifies that a credit report will not be required. I'd be certain that you really want to take the HP (or maybe 2) for a CLI on that card. Over the years I took a lot of them and Citi never budged on my starting line of $1250 for the Home Depot card (closed it and opened a Lowe's with $17k SL) but when we asked for $10k (from $2k) on the Best Buy card, it was approved immediately.
Would it be a semi-auto CLI if you log in and there is a message from Chase on the main account screen prompting you to ask for a SP CLI? My wife has received a Citi SP CLI. Things have surely changed drastically since then, but in 2002 I was sent a "convenience check" from Citi offering to increase my credit line on the Shell card from $500 to $2025 if I used it. I did, they did and that $25 at the end of the credit line has given me OCD issues ever since. I bring it up because I didn't get a new inquiry from that, and it wasn't technically an auto-CLI.
