US card application rules: Chase 5/24, Citi 8/65, Amex once-per-lifetime and the rest

Every US card issuer protects itself from fast, repeated applications, and most protect their bonuses from repeat claimants. The limits are rarely printed in one place. This guide gathers the ones reviewers documented in September and October 2026 so you can check your own position before you apply, because a hard inquiry spent on a card you were never going to get is a real cost.

Two kinds of rule

Velocity limits cap how many cards you can open in a window. They are about how many new accounts you have, whoever issued them. Bonus rules decide when you can earn the same sign-up offer again. Mixing the two up is the most common mistake: you can pass a velocity limit and still be refused a bonus.

How to count

1. 1

   New accounts in 24 months

   Open your credit report and count every credit card account opened in the last 24 months, with any issuer. That is the number Chase's 5/24 and Barclays' 6/24 look at. The guide to reading your credit report shows where to find open dates.

2. 2

   Hard inquiries in 6 months

   Citi and Barclays weigh recent hard inquiries heavily. Reviewers suggest fewer than three in the past six months for the Strata Premier and fewer than six for a Double Cash or Barclays card. The difference between soft and hard inquiries matters here.

3. 3

   Date of your last bonus

   Write down the month you earned each bonus, not the month you opened or closed the card. Freedom's 24 months and Venture X's 48 months run from the bonus date.

4. 4

   Cards you already hold

   Chase refuses a Sapphire bonus if you hold another personal Sapphire. Amex can refuse a Gold bonus if you ever held a Platinum. Check the family before you apply.

The order of operations these rules imply

1. 1

   Count new accounts and inquiries

2. 2

   Apply to the rule-limited issuer first

3. 3

   Space the others out

4. 4

   Note each bonus date

5. 5

   Re-check before the next card

Because Chase's 5/24 counts accounts opened anywhere, anything you open elsewhere makes a later Chase application harder, so people who want a Chase card tend to apply for it before they collect other new accounts. Amex does not look at 5/24 or the number of inquiries, so it is the easier one to leave until later. Citi and Capital One want space between applications, so one a quarter is a safer pace than one a month.

How long a credit history to have

If you have less history than that, start lower in the ladder. The newcomer guide and the guide to secured cards cover the first steps, and the picks by spending style show what to move to next.
