Worried about your overseas remittance being rejected or funds frozen? The key lies in whether you understand and comply with Anti-Money Laundering (AML) and Know Your Customer (KYC) requirements. The global scale of personal fund flows is growing rapidly, driving a comprehensive upgrade in regulations.
- Global remittance volume reached a record 818 billion USD in 2023.
 - Of which, remittances to low- and middle-income countries are estimated at 656 billion USD.
 
To ensure funds are legal and secure, users must go through compliant financial institutions and provide authentic proof of personal identity, source of funds, and remittance purpose as required.

To ensure the stability and security of the global financial system, regulatory authorities in various countries have established two key defense lines: Anti-Money Laundering (AML) and Know Your Customer (KYC). Understanding these two rules is crucial for users before conducting any fund operations.
AML is a set of laws and procedures aimed at combating illegal fund flows. Its goal is to prevent criminals from using the financial system to “launder” illicit proceeds. KYC is the core execution component under the AML framework. Financial institutions verify customers’ true identities and assess potential risks through the KYC process.
A standard KYC process typically includes three pillars:
In short, AML sets the rules, while KYC is the specific action financial institutions take to comply with them.
Any attempt to bypass compliance requirements will trigger severe consequences. For individuals, the most direct risks are remittance failure, prolonged fund freezes, or even confiscation. Once suspicious transactions are detected, financial institutions have the right and obligation to immediately suspend operations and report to regulators.
Financial institutions that fail to strictly implement AML regulations also face harsh penalties from regulators.
For example, TD Bank faced a massive 3 billion USD fine for failing to effectively monitor and report money laundering activities linked to drug trafficking groups. This demonstrates regulators’ zero-tolerance attitude toward compliance failures.
Additionally, individuals may face legal action. In the United States, individuals intentionally evading sanctions or export control laws, even if not U.S. citizens, may face criminal charges. Under relevant regulations, such as the USA PATRIOT Act, violators can face up to 20 years in prison and a 1 million USD fine. Therefore, compliant operations are not only a prerequisite for successful overseas remittances but also a necessary safeguard to protect individuals from legal sanctions.
After understanding AML and KYC rules, users need to prepare a complete and authentic set of materials. Financial institutions’ compliance reviews mainly revolve around three core questions. The key to passing the review is providing clear and credible answers to these three questions. These three key materials form the foundation of the user’s KYC file.
Identity verification is the first and most basic step in the KYC process. Financial institutions must confirm that the person operating the account is the legitimate identity holder they claim to be. This is not only to prevent identity theft but also to establish a traceable transaction record.
Typically, complete identity verification requires two types of documents:
Note: Proof of address has strict timeliness requirements. Financial institutions typically only accept recently issued documents. For example, utility bills generally cannot be older than 3 months, while bank statements may be accepted within 6 months.
| ✅ Acceptable Proof of Address | ❌ Unacceptable Documents | 
|---|---|
| Utility or gas bills from the past three months | Copies of any documents | 
| Bank or credit card statements from the past six months | Mobile phone bills | 
| Government-issued tax documents or official letters | Shopping invoices or receipts | 
| Valid lease agreements | Library cards or membership cards | 
Proving the source of funds is the core of Anti-Money Laundering (AML) review. Users must clearly explain the legitimate source of the money to prove it is not from criminal activities. Financial institutions will require different levels of proof based on the remittance amount and user risk rating.
Here are some common fund source scenarios and their corresponding proof document examples:
| Fund Source Scenario | Proof Document Examples | 
|---|---|
| Salary Income | - Pay slips for the past 3-6 months- Bank statements showing salary deposits- Income verification letter from employer | 
| Property Sale | - Final sales contract signed by both parties- Confirmation letter from lawyer or regulated accountant- Bank statement showing property payment receipt | 
| Investment Income | - Brokerage statements for stocks, funds, etc. (e.g., from U.S. market brokers)- Bank transaction records showing investment income | 
| Parental Gift | - Gift Deed signed by the donor- Donor’s source of funds proof (e.g., pay slips or bank statements)- Household register or birth certificate proving family relationship | 
When preparing these documents, the key is to ensure all files are interconnected to form a complete evidence chain. For example, the contract amount for a property sale should match the funds received in the bank.
Clearly stating the remittance purpose is the final step in completing compliance review. Financial institutions need to ensure the final destination of funds is legal and reasonable. Unclear or sensitive purpose descriptions are common reasons for overseas remittance delays or rejections.
When filling in the remittance purpose, users should use standard, specific, and unambiguous terms.
Pro Tip: Use internationally recognized English terms directly To avoid misunderstandings from translation, it is recommended to fill in standardized English purposes directly. For example, some countries (such as India) have specific codes for certain purposes in their financial systems, such as
P1505for education-related cross-border remittances, highlighting the importance of standardized purposes.
Recommended Standard Terms:
Tuition Fee (Paying tuition)Living Expenses (Living expenses)Family Support (Family support)Medical Bill Payment (Paying medical bills)Salary Repatriation (Salary repatriation)⚠️ Beware of High-Risk Terms Users should avoid vague or terms that may trigger additional scrutiny. For example, words like “investment,” “loan,” “business dealings,” or “consulting fees” will immediately alert financial institutions. These purposes typically require complex business contracts, company documents, and tax proofs, significantly increasing compliance difficulty and time costs for personal remittances.
In summary, providing authentic, accurate, and clear materials is the best strategy to ensure funds are safe and arrive quickly.

Preparing compliant materials is the first step to successful remittance, while choosing a safe and efficient channel is another key to ensuring funds arrive smoothly. There are numerous remittance channels in the market, from traditional banks to emerging fintech platforms, each with its pros and cons. Users need to carefully screen to find the most suitable solution under compliance.
When making overseas remittances, users mainly face two choices: long-established traditional banks and flexible, efficient licensed remittance platforms. The two differ significantly in service models and compliance processes.
| Feature | Hong Kong Licensed Banks | Licensed Remittance Platforms (e.g., Wise, Remitly, BiyaPay) | 
|---|---|---|
| Arrival Time | Slower, usually 1-5 business days, affected by SWIFT network and holidays. | Fast, with multiple options; express can arrive in minutes. | 
| Fees and Exchange Rates | Complex fee structure, may include cable fees, correspondent bank fees, and large exchange rate spreads. | Transparent fees, usually a single service fee, with exchange rates closer to mid-market rates. | 
| User Experience | Relatively cumbersome process, may require in-person visits, limited online tracking. | Fully online operation, smooth App experience, real-time transaction tracking. | 
| Compliance Process | Strictly follows regulatory requirements, mature KYC process, suitable for large or complex transactions. | Equally strictly regulated, digitized KYC process, users submit materials online. | 
Traditional banks, such as licensed banks in Hong Kong, have advantages in handling large or complex commercial remittances due to their extensive networks and brand reputation. However, for regular personal remittances, their longer processing times and higher overall costs are obvious shortcomings.
In contrast, licensed remittance platforms perform better in speed, cost, and convenience. These platforms are subject to equally strict financial regulation. For example, platforms operating in the U.S. must obtain a license from the Financial Crimes Enforcement Network (FinCEN). Users can verify a platform’s legitimacy by visiting the regulator’s official website, such as the UK Financial Conduct Authority (FCA) online registration system.
Data Security is Core Compliant remittance platforms place great emphasis on user data protection. Take BiyaPay as an example; it not only uses two-factor authentication and end-to-end encryption technology but also strictly complies with international regulations such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA). This means:
- Transaction details are only visible to the sender and recipient, preventing third-party review.
 - Users have the right to know how their personal data is used and can request deletion at any time.
 
Choosing a licensed platform not only provides a better remittance experience but also ensures personal information and funds receive bank-level or even higher security protection.
When choosing remittance channels, users must stay vigilant and proactively identify and avoid potential risks. Any operation deviating from the regular financial system may lead to fund loss or legal issues.
Here are some “high-risk signals” to be highly alert to:
⚠️ Scam Warning Scammers often impersonate well-known brands and use phishing websites to trick users into entering private keys or account information. Users should never access financial services or provide sensitive personal information via non-official links.
When the remittance amount is large, financial institutions have a legal obligation to report to regulators. Users need to understand these regulations to ensure smooth transactions. This is not a restriction on remittances but a standard procedure under the anti-money laundering framework.
Before making large remittances, the best practice is to consult your chosen bank or remittance platform in advance to understand their specific reporting process and required documents, ensuring everything is foolproof.
After successfully submitting a remittance application, the user’s work is not over. Understanding how to track fund status and handle unexpected issues is the guarantee for ensuring funds ultimately arrive safely.
Different remittance channels provide different tracking methods. Users can adopt the corresponding tracking method based on their chosen service.
When discovering that an overseas remittance has not arrived for a long time, users should first remain calm, as most issues can be resolved through clear communication and supplementary materials.
Common Cause Analysis Remittance delays or freezes are usually not due to lost funds but triggered by financial institutions’ compliance reviews. Common reasons include:
- Information Errors: Spelling errors in recipient’s name, account, or SWIFT code.
 - Compliance Alerts: Large transaction amounts, abnormal remittance patterns, or unclear purpose descriptions trigger automatic flags in the Anti-Money Laundering (AML) system.
 - Missing Documents: The institution requires additional source of funds or purpose proof, but the user fails to submit in time.
 
If funds are frozen, users should proactively take the following steps:
Proactive communication and providing authentic and complete proof are the most effective ways to resolve remittance delay or freeze issues.
Choosing compliant channels, preparing authentic materials, and clearly stating the purpose are the three pillars to ensure funds are legal and secure. Compliance is not only about meeting regulatory requirements from institutions like the Financial Action Task Force (FATF) but also the fundamental guarantee to protect personal funds from being embezzled or frozen.
Action Recommendation: Users should prioritize compliance in every remittance and never take unnecessary fund and legal risks for temporary convenience.
Financial institutions must comply with Anti-Money Laundering (AML) regulations. All transactions, regardless of amount, may trigger compliance reviews. This is to identify and prevent money laundering patterns using small transactions.
Student users can provide a Gift Deed signed by their parents, along with their parents’ source of funds proof (such as pay slips or bank statements). This forms a complete chain of legitimate fund evidence.
Absolutely not. Using a third-party account for remittance is a serious compliance red line. Financial institutions cannot verify the true remitter’s identity and source of funds and will usually reject such transactions directly to avoid money laundering risks.
The remitter must ensure the recipient’s name fully matches the bank account information, including order and spelling. Any minor difference may cause remittance failure or delay. Verify carefully with the recipient before remitting.
