dentification Requirements
To open a US credit card, issuers typically require:
- Social Security Number (SSN): Standard for US citizens and authorized resident workers.
- Individual Taxpayer Identification Number (ITIN): Accepted by several major issuers (such as American Express, Capital One, and Citi) for individuals without an SSN.
- US Physical Address & Bank Account: Required for identity verification and bill payments.
The FICO Score Breakdown
Your credit card activity directly reports to three major credit bureaus (Experian, Equifax, TransUnion) to generate your FICO Score (ranging from 300 to 850):
- Payment History (35%): Paying at least the minimum balance on time every month.
- Credit Utilization Ratio (30%): The percentage of your credit limit in use. Keeping this below 10% to 30% optimizes your score.
- Length of Credit History (15%): The average age of all your accounts.
- New Credit & Inquiries (10%): Hard inquiries generated when applying for new lines of credit.
- Credit Mix (10%): The variety of accounts (revolving cards vs. installment loans).

3. Leading US Reward Ecosystems
The US market is dominated by transferable reward currencies that yield the highest redemption value when transferred directly to airline and hotel loyalty programs:
Chase Ultimate Rewards (UR)
- Key Feature: High point flexibility (transfers 1:1 to partners like United, Southwest, and Hyatt) and strong travel protections.
- The “Chase 5/24 Rule”: Chase will automatically reject applications if you have opened 5 or more personal credit cards across any bank in the past 24 months.
- Common Strategy (Chase Trifecta): Pairing a premium card (Sapphire Preferred/Reserve) with no-fee cash back cards (Freedom Unlimited, Freedom Flex) to combine and transfer all points.
American Express Membership Rewards (MR)
- Key Feature: Expansive global airline transfer partners (e.g., Delta, British Airways, Air France/KLM, Emirates) and luxury lifestyle credits.
- Application Rule: Amex enforces a “once-in-a-lifetime” rule for welcome bonuses on specific card tiers.
Capital One & Citi
- Capital One: Known for straightforward 2x miles structures and no foreign transaction fees across all cards.
- Citi ThankYou Points: Offers strong everyday category multipliers (e.g., 3x–5x on custom categories) paired with airline partners.
4. Key Rules for Managing US Credit Cards
- Statement Balance vs. Minimum Due: Always pay the Statement Balance in full by the due date. Paying only the “Minimum Payment” avoids late fees but incurs high APR interest (typically 20%–30%+).
- Foreign Transaction Fees (FTF): If using a US card abroad, verify whether it waives foreign transaction fees (usually 3% per transaction on cards with FTF).
- Product Changes (Downgrades): If a high-annual-fee card no longer fits your spending after year one, you can often “downgrade” it to a $0-annual-fee card within the same family to preserve your credit line and account age.
