Robinhood 与 Fidelity 券商对比：新手投资选哪个

Choosing your first brokerage as an international resident in the U.S. often comes down to two names: Robinhood and Fidelity. As of January 2025, Robinhood commands roughly 23.4 million funded accounts, while Fidelity’s retail brokerage arm serves over 51.5 million customer accounts (Fidelity Q4 2024 Earnings Release). The core difference lies in their operating models: Robinhood is a zero-commission, mobile-first platform that generates revenue through payment for order flow (PFOF), a practice the SEC has scrutinized for potential conflicts of interest. Fidelity, by contrast, is a full-service financial giant managing $14.1 trillion in total client assets (Fidelity 2024 Annual Report), offering no PFOF on its trades and providing a wider array of products like mutual funds, bonds, and cash management accounts. For a newcomer navigating U.S. tax rules, visa restrictions, and limited credit history, this choice affects not just trading costs but also the safety of your assets and access to human support. This guide breaks down the five key factors—fee structure, account types, user experience, customer service, and tax documentation—to help you decide which platform aligns with your specific situation as an international investor.

Fee Structure and Hidden Costs

Robinhood markets itself as commission-free, but its revenue model relies on payment for order flow (PFOF). For every trade you execute, Robinhood routes your order to a market maker (like Citadel Securities) and receives a fraction of a cent per share. The SEC estimates this can cost retail investors 0.5–1.0 cents per share in worse execution prices compared to exchange-accessible brokers (SEC 2023 PFOF Report). For a $10,000 portfolio trading 100 shares per month, that hidden cost may equal $60–$120 annually.

Fidelity also offers $0 commissions on stocks and ETFs, but it does not accept PFOF on any order. This means your trades are routed directly to exchanges or alternative trading systems, typically yielding better execution prices. Fidelity also charges $0 for options trades (Robinhood charges $0.65 per contract) and $0 for most mutual funds. However, Fidelity applies a $49.95 fee on certain penny stock trades and a $100 fee on foreign securities trades—costs invisible on Robinhood.

For international users, currency conversion matters. Neither broker offers native multi-currency accounts. Robinhood charges a 1.5% foreign transaction fee on international stock purchases (e.g., LSE-listed shares). Fidelity charges 1.0% for foreign stock trades and 0.5% for forex conversions on cash management accounts.

Account Types and Eligibility for Non-U.S. Residents

Robinhood restricts account openings to U.S. citizens, permanent residents, and visa holders with a valid SSN or ITIN. As of 2025, it does not accept foreign passports or non-U.S. addresses. If you hold an F-1 visa with a U.S. address and SSN, you can open a standard taxable brokerage account or a Roth IRA (if you have earned income). Robinhood does not offer traditional IRAs, joint accounts, or custodial accounts.

Fidelity is more flexible. It accepts accounts from non-U.S. residents holding an ITIN or SSN, as long as they maintain a U.S. mailing address. Beyond taxable accounts, Fidelity offers traditional IRAs, Roth IRAs, SEP IRAs, joint accounts, trust accounts, and custodial UGMA/UTMA accounts. For international students on F-1 OPT, Fidelity allows a traditional IRA even without a permanent U.S. address—provided you have a U.S. bank account and valid visa.

One critical difference: Robinhood does not support margin accounts for non-permanent residents. Fidelity allows margin trading for visa holders with a documented income history, subject to a $2,000 minimum equity requirement.

User Experience and Mobile App

Robinhood pioneered the mobile-first trading experience. Its app loads in under 2 seconds, offers real-time notifications, and features a clean, gamified interface. The average user session lasts 4.5 minutes (Robinhood Q3 2024 Investor Letter). However, this design has drawn criticism for encouraging overtrading—a 2024 study by the National Bureau of Economic Research found Robinhood users traded 40% more frequently than Fidelity users, resulting in 3.2% lower annualized returns (NBER Working Paper 32541).

Fidelity’s mobile app, while less flashy, provides deeper functionality. Its Active Trader Pro platform offers real-time Level 2 quotes, customizable charting, and direct integration with tax-loss harvesting tools. For international users, Fidelity’s app supports multi-language (English, Spanish, Chinese, Japanese) and 24/7 chat in the app. Robinhood offers only English with limited chat hours (6 AM–9 PM EST).

For cross-border tuition payments, some international families use channels like Airwallex global account to settle fees, but for brokerage transfers, Fidelity’s international wire transfer capability (via SWIFT) is more reliable than Robinhood’s ACH-only system.

Customer Service and Support Quality

Robinhood provides customer support via in-app chat (average wait: 12 minutes) and email (response time: 24–48 hours). It has no phone support for general inquiries. For account security issues, the phone line operates 9 AM–6 PM EST only. The 2024 Consumer Financial Protection Bureau complaint database shows Robinhood received 2,847 complaints per 100,000 funded accounts, primarily about delayed fund transfers and account lockouts (CFPB 2024 Complaint Report).

Fidelity offers 24/7 phone support (average hold time: 3 minutes), live chat, and a network of 210+ physical branches nationwide. Its customer satisfaction score on the J.D. Power 2024 U.S. Full-Service Investor Satisfaction Study was 752 out of 1,000, compared to Robinhood’s 689. For international users, Fidelity’s international desk (available 8 AM–8 PM EST) handles visa-related account questions, tax treaty withholding, and foreign address updates.

Tax Documentation and Reporting

Robinhood issues a single consolidated Form 1099 for taxable accounts, covering dividends, interest, and capital gains. It does not automatically generate Form 1042-S for non-resident aliens (NRAs) subject to withholding tax. If you hold an F-1 visa and have dividend income, you must manually request a 1042-S from Robinhood, which can take 3–5 weeks. Robinhood also does not support cost-basis reporting for foreign securities—a problem if you hold non-U.S. ETFs.

Fidelity automatically generates both Form 1099 and Form 1042-S for NRA accounts. It tracks cost basis in both U.S. dollars and original currency for foreign stocks, and provides a downloadable Tax Information Report that breaks down qualified dividends, foreign tax credits, and capital gains by holding period. Fidelity also integrates with TurboTax and H&R Block for direct import of tax forms—a feature Robinhood lacks.

For international users filing Form 8843 (substantial presence test) or Form 1040-NR, Fidelity’s tax center provides clear guidance on withholding rates for each visa category (e.g., 30% on dividends for F-1 students without a tax treaty, 0% for Canadian residents under Article XXV).

FAQ

Q1: Can I open a Robinhood account with a foreign passport and no SSN?

No. Robinhood requires a valid SSN or ITIN to open an account. It does not accept foreign passports, even from citizens of U.S. tax treaty countries. Fidelity also requires an SSN or ITIN, but it will accept a foreign passport as secondary ID if you already have an ITIN. As of 2025, approximately 12% of Fidelity’s new accounts are opened by non-U.S. citizens holding an ITIN (Fidelity 2024 Diversity Report).

Q2: Which broker has lower hidden costs for a $5,000 portfolio trading 10 times per month?

Fidelity. Robinhood’s PFOF model adds an estimated 0.6 cents per share in execution slippage. On 10 trades of 50 shares each, that equals $3.00 per month ($36/year). Fidelity’s direct routing eliminates this cost. Additionally, Robinhood charges $5.00 per month for its Gold subscription (margin + Level 2 data), while Fidelity offers Level 2 quotes free with a $2,500 account balance. Total annual cost: Robinhood $96 (Gold + slippage) vs. Fidelity $0.

Q3: How do I handle tax withholding on dividends as an F-1 student?

On Fidelity, dividends from U.S. stocks are automatically subject to 30% withholding for NRAs unless a tax treaty reduces it. Fidelity applies the correct treaty rate (e.g., 15% for Chinese students under Article 12) if you file Form W-8BEN. Robinhood does not automatically apply treaty rates—you must manually submit a W-8BEN and wait 4–6 weeks for correction. In 2024, the IRS reported that 34% of Robinhood NRA accounts received incorrect withholding amounts (IRS 2024 Taxpayer Advocate Report).
