Just wanted to give a heads up to everyone considering a Citi CLI. Few months ago I requested a CLI on my Citi Dividend and went from initial $4000 to $5500. Then today I requested a CLI on my Citi Forward, and they matched the same limit. $4000 to $5500. Both done with soft pulls and minimal use on the cards. I only have 1 reoccuring bill on each to keep the card active, always PIF.
Congratulations! 
I love my Citi Diamond Preferred - not a ton of rewards, but I asked for/received a $1000 CLI with a SP only in April (it seems like GE cards, Amex, and Citi are the only ones allowing/granting requests with SP - BoA and Chase are pretty much a guaranteed HP). I plan to keep asking regularly to help get my limit up there...
For xiownthisplacex - You can ask for a CLI six months after you get your card, and every 6 months thereafter (typically with a SP only). I asked for my CLI when I'd had the card for 8 months, and it was approved.
Yes 6 months after opening card, or after the 6th statement.
Congrats Transplant! I love the SP CLI's.

You certainly can try, it also might result in another HP, depends if its worth it to you. I suppose you could tell them you won't even activate the card if they don't grant your request, but you already took the INQ for it, midas well keep it and ask for a CLI in 6 months.
