<prompt> Human: I moved to the U.S. a few years ago, and in 2009 I finally got a credit card, but all they would give me was a 400 limit. Every six months or so Ive been asking for an increase to something more reasonable, but they will only increase my limit by about 500 each time. Gradually over the last four years Ive gotten my limit up to 2900, but thats still lower than I would like -- it often prevents me from using the CC for big purchases like vacations. Ideally I would like a limit somewhere in the 5k-10k range, so that I dont always have to keep my rough current balance in the back of my head.Im wondering if Im doing something wrong when requesting a limit increase. Essentially, I message them every six months or so saying please increase my limit; they message back asking for my income and what I would like my credit increased to; I say something like 175k this is true, but theyve never asked for proof, so I wonder if they doubt it? and 5k; and then they say your request is higher than we can give, here is a 500 increase. Ive checked my credit and there are no blemishes. Creditkarma says I have a score around 760. I dont use debt for anything else -- I rent, own my car outright, etc.Am I doing something wrong, or is this unavoidable? I have a ton of poorer friends with much higher credit limits, so I feel like there must be something I am doing wrong.Edit: Thanks for the suggestions everyone! Id prefer not to apply for a new card, just because Id prefer not to carry two cards around and this one has fantastic rewards its an Amazon card, and I do most of my shopping on Amazon. Im going to try blueboybobs suggestion of pretending to buy something big, and then if that doesnt work Ill apply for a different card.  <response>: Any reason you cant apply for another card that has huge limit by design? You probably have credit cards that are designed for people with low income and less than stellar credit.
