The application rules each issuer runs: the Chase 5/24 rule, Amex lifetime language, Citi and Capital One 48 month clocks, and the business card exemption that threads between them. Application order follows from these rules, so start here before applying for anything. Two of these rules are published by the issuer: the Citi 48 month clock and the Amex once per lifetime language. Every other threshold on these pages is observed from applicant reports, and each guide states which it is and where the claim comes from.
American Express pays each card’s welcome offer only once per lifetime, and the count runs per card. Before you apply, take the time to confirm the offer will actually pay on your application history.
