I only have a Citi DC. You can call them and try to request a larger CL. I recommend doing a search on these boards to learn DPs for this specific card.

Too soon to tell, give it some time. Good luck!!!
Citi's bank cards and CBNA retail cards are completely different. I would certainly advise waiting until the card has been opened for at least 6 months, after using it and making payments. I didn't have great luck with the card myself. I was given a $1000 starting line in 2011, used it all the time, making large purchases and paying them off. I took 4 or 5 HPs the last 2 years that I had the card, and I was still being denied for a CLI increase on it even with decades of flawless credit history, good scores (730s-760s at the time), and a fairly high income.
In late 2016, I finally gave up, closed my $1,000 Home Depot card, and within minutes had a $17,000 Lowe's card which soon grew to $25k and then $35k. I also opened an actual Citi credit card a few days after my last CLI denial on the Home Depot card and was approved for many times that card's limit, and today that card has a credit line over $20k without ever taking another HP. Like I said, Citi bank cards and CBNA store cards are completely different.
There certainly are examples of others who have had better luck with the Home Depot card, of course, but if you were approved for $500 I would not count on that growing in the near future.
I've considerd the Home Depot a fewtimes, but the DP's of getting small SL put sme off. I mean what use is a "Home Improvement" card if it can't even handle the load? Oh hey I can buy the sink and a toilet one month, then slowly buy everthing else every month after. lol
What happens if i need to buy a fridge though?

The card came with a $500 CL. I'm not looking to go crazy, but would like to ask for $1K or $1500 CLI. Anyone have experience with this? I know the Lowe's card used to be good for this sort of thing right away, but since every bank is different and Synchrony is basically freaking out right now, I went this route. I have never had a Citi card before, so unsure. Any thoughts are appreciated, thanks in advance!
Can't speak from experience, but the SL and limited CL have made me not want to invest into the Home Depot card. Was looking into the Lowes card since it had better incentives. Unfortunately comparing HD to Lowes, it seems HD typically has the better prices...
