Whenever you apply for a new credit card issuer bank will do a “hard inquiry” (aka “hard pull”) on your credit history to verify your creditworthiness. So it is a chicken-and-egg problem, to build good creditworthiness and build credit history you need a credit card and applying a new card impacts your score, so you need to plan ahead and apply for a few cards together and start building a good credit history by regularly using and repaying credit cards.
