Opening a new line of credit is only a temporary hit to your score. Multiple cards in a short time will be a bigger hit, but it’ll eventually pass.
Most if not all of those cards offer a free credit report that could tell you how much of an impact this had on your score and how quickly it improves. If you have another existing card (don’t sign up for another one) you may be able to see the change to your score once these hard credit pulls hit your credit report.
If not, wait a month or so and use one of your free annual credit reports. You get one report per year from each agency for free, with no consequence to your credit score. There’s 3 credit agencies, so in principle you can check your credit every 4 months for no cost.






I used to live about that distance from my work. I only walked it occasionally, if the weather was nice, I had the time to spare, and a little extra energy. Generally I took the bus.
I think 30 minutes is about how long I’d walk to get somewhere before considering public transit or driving.
