I am a new credit builder and just wondering- I have seen in the forums that after some number of days with a new card you can ask for your limit to be.. tripled? Is this with all cards or only certain companies? Is there any downside- HP, etc? I don't need the extra funds but I would like to learn how to increase limits this way just to keep my util low and boost my score. Any info is appreciated. Thanks to all!

Every creditor sets their own policy for CLIs. Some, like Cap1, never ( with few exceptions ) grant consumer initiated CLIs.
I believe that you are referring to AMEX ~ they allow you to request a 3X CLI after 60 days or so.
Most creditors will pull your credit as part of their CLI review process.
