As you’re starting to build credit, don’t forget to Freeze all 3 bureaus and only thaw them as needed
And with Chase remember that you can peanut butter available credit across multiple cards. So when you get that 2nd/3rd/4th card and they say (e.g.) “we don’t want to extended any more credit than $10k” - you can ask them to apply $5k on Sapphire, $3k on Cashback card, $2k on Amazon rewards”. When you close a Chase card, always tell them which remaining card to merge its available credit to.
