Are you considering opening a Hong Kong U.S. stock account? Futu NiuNiu and Tiger Securities are undoubtedly popular choices. Taking Tiger Securities as an example, its global account total reached 2.53 million by the first quarter of 2025, demonstrating strong market appeal.
This article directly compares the differences between the two to help you clarify key information about Futu NiuNiu account opening and Tiger Securities application, assisting you in making an informed decision quickly.
Before starting the online application, preparing all required documents in advance can make your account opening journey twice as effective with half the effort. The document requirements for Futu NiuNiu and Tiger Securities are largely similar, mainly revolving around two core proofs: identity and address.
No matter which broker you choose, the following two types of documents must be prepared in advance:
Important Tip: Most address proof documents (such as bills) are required to be issued within the last 3 to 6 months. Check the document date before uploading to avoid review delays due to expired files.
The table below lists common address proof options:
| Document Type | Key Requirements |
|---|---|
| Bank or Credit Card Statement | Must include your name, full address, and bank name. |
| Utility Bill | Such as water, electricity, gas, or internet bills, must show name and address. |
| Government Agency Letter | Tax bills, social security notices, or other official documents. |
| Valid Driver’s License | If the license shows your current address, it can serve as valid proof. |
| Lease Agreement or Property Deed | Must clearly show your name and address information. |
Depending on your specific situation, the broker may require additional information for verification.
With the above documents prepared, you can smoothly proceed to the next online application process.

After understanding the required documents, the next step is to compare the core account opening conditions of the two brokers. These conditions directly affect whether you can open an account smoothly and the efficiency of opening. This section will use intuitive tables and clear explanations to help you quickly grasp the key threshold differences between Futu NiuNiu and Tiger Securities.
First, you need to confirm if your region is supported by the broker.
Please Note: According to its compliance statement, Tiger Securities is not authorized to solicit investors in mainland China, Malaysia, and Vietnam and certain jurisdictions.
Besides regions, your age and occupational status also affect the account types you can open. Both brokers generally follow these standards:
| Age and Status | Available Securities Account Types |
|---|---|
| Under 18 | Cannot open an account |
| 18 to 21 years old | Cash account only |
| 21+ (student or unemployed) | Cash account only |
| 21+ (stable income) | Cash or margin account |
During the application, you need to fill in occupation, income, net assets, etc.. This information helps the broker assess your investment experience and risk tolerance to match appropriate account permissions.
As mentioned earlier, identity and address proof are the cornerstone of account opening. Both brokers accept valid ID cards or passports as identity proof.
Selection Tip: Although the types of address proof documents accepted by both brokers are largely similar (such as utility bills, bank statements, etc.), review strictness may vary slightly. If your address proof is not very “standard,” you can check which broker’s customer service is more flexible or accepts a wider range of alternative documents.
Overall, as long as you provide clear, valid, and recent proof documents, you usually won’t encounter major obstacles at this step.
Funding threshold and review speed are the two issues users care about most, directly affecting when you can start your first trade. The table below clearly compares the core differences:
| Comparison Dimension | Futu NiuNiu | Tiger Securities |
|---|---|---|
| Minimum Deposit Threshold | $1,300 | $0 |
| Account Review Time | Usually 1 to 2 business days | As fast as a few minutes |
From the table:
Ultimately, your choice can be based on funding preparation and speed preference. If you want to start immediately with funds ready, both are good options. If you want to open an account first and plan funding later, Tiger Securities’ zero-threshold policy suits you better.
