Call HSBC and ask for CLI
Apply for Capital One but be prepared for another $300 limit but at least it does have credit steps that gives you cli every 6 months and sometimes you can call right before the 6 months and get additional cli.
Is HSBC your only credit period right now?
in that case I would also suggest like a target or Macy's if you shop at either, I prefer Macy's because you can get CLI every 3 months without additional credit pulls and eventually get a visa with them
