Your best first try is Capital One Quicksilver Student through its no-impact eligibility check; use Zolve if you have no SSN, or Capital One Platinum Secured if you receive no suitable unsecured offer.
“I am a 21-year-old international student making around $35k per year working part-time. What is the best credit card to help me start building my credit score and history?”
Summary
You are old enough for the ordinary age-21 application rule, and Regulation Z expressly recognizes part-time wages as income when they are current or reasonably expected. You can test the strongest first option without hurting your score, then use a clear fallback instead of sending several applications.
Your best route forks according to which identity document the issuer accepts and whether its no-impact eligibility check gives you an unsecured offer.
Start here if Capital One's accepts your identity information. It has a $0 annual fee, earns 1.5% cash back on purchases, and is available to students currently enrolled—or admitted and planning to enroll within three months—at an accredited higher-education institution. The eligibility check itself has no credit-score impact.
Use this branch if lack of an SSN blocks the mainstream student-card route. Zolve's current product page says “No SSN,” “No Annual Fees,” and that responsible use may help improve your credit score; approval and the limit remain individualized. Because the fetched page did not publish a fixed APR or deposit requirement, this is the identity-access route, not a fully cost-ranked winner.
Use this only if the unsecured eligibility checks produce no suitable offer and you can lock up a refundable deposit. This has a $0 annual fee, requires a $49, $99, or $200 minimum refundable deposit depending on the offer, starts with at least a $200 line, and reports card status to all three major credit bureaus.
No card can guarantee a score increase; your payment history, balances, and time using credit matter.

Next steps
These steps let you test an unsecured student card first, preserve your score, and still open a bureau-reporting fallback if needed.
Before any application
Calculate the income you can truthfully list
Use about $35,000 only if it reflects current or reasonably expected income available to you. Regulation Z expressly includes part-time wages; it does not let you count inaccessible family income merely because you are a student.
Requirements
First choice
Run the Quicksilver Student eligibility check
Go directly to https://www.capitalone.com/credit-cards/quicksilver-student and use “Check My Eligibility” before applying. The check has no score impact; the current comparison page lists a $0 annual fee and 1.5% cash back on every purchase.
Requirements
No-SSN branch
Use Zolve if an SSN is the blocker
Apply at https://zolve.com/us/credit-card only if the mainstream route cannot accept your identification. Zolve's product page says no SSN and no annual fee; it says limits can reach $15,000 but depend on approval, verified income, creditworthiness, and other eligibility criteria.
Requirements
Fallback
Use Platinum Secured if there is no unsecured offer
Use https://www.capitalone.com/credit-cards/platinum-secured. It has a $0 annual fee, opens with at least a $200 line after the required deposit, and regularly reports to all three major credit bureaus; its current variable purchase APR is 28.99%.
Requirements
As soon as the card opens
Automate full payment and keep the balance low
Set autopay for the full , not only the minimum. Keep reported below 30% of the limit and never spend merely to earn rewards; the CFPB says carrying a balance is unnecessary for a good score.
Requirements
After the account begins reporting
Review your free credit reports
Use only https://www.annualcreditreport.com. The FTC says it is the authorized site and that Equifax, Experian, and TransUnion each provide a free report once a week; reviewing your own report does not hurt your score.

Legal sources
This answer is grounded in CFPB Regulation Z and credit guidance, FTC and IRS guidance, and the issuers' current product terms.
12 CFR 1026.51
Because you are already 21, the regulation's special under-21 application rule does not govern your application.
Official interpretation of § 1026.51(a)(1), example 5
Assume that an applicant is not employed and that the applicant is age 21 or older so § 1026.51(b) does not apply.
12 CFR 1026.51(a)
Current or reasonably expected part-time wages are an allowed income type for the issuer's ability-to-pay review.
Official interpretation of § 1026.51(a)(1), paragraphs 5-6
Current or reasonably expected income includes, for example, current or expected salary, wages, bonus pay, tips, and commissions. Employment may be full-time, part-time, seasonal, irregular, military, or self-employment.

CFPB Ask CFPB No. 318
The CFPB confirms that carrying debt is unnecessary and paying in full minimizes interest while supporting good scores.
You don’t need to carry a balance on credit cards to get a good score. In fact, you don’t need outstanding debt at all. Paying off the balance in full each month helps get you the best scores and keeps your interest costs as low as possible.
CFPB Ask CFPB No. 1317
A full application can affect your score, unlike a soft pre-eligibility review.
Hard inquiries. These are often inquiries by lenders after you apply for credit to help them decide whether they will approve your loan or credit. These inquiries will impact your credit score because most credit scoring models look at how recently and how frequently you apply for credit.
FTC Free Credit Reports guidance
The FTC identifies the authorized site and the permanent free-weekly report program.
The three nationwide credit bureaus have permanently extended a program that lets you check your credit report from each once a week for free at AnnualCreditReport.com.
IRS ITIN guidance
An ITIN may identify a taxpayer but does not confer employment authorization.
An ITIN is issued by the IRS for federal tax purposes only. An ITIN doesn't: Authorize you to work legally in the U.S.
