Thailand has introduced several visa pathways to attract foreign investment and talent, but none are as tailored to the needs of modern professionals as the Smart Visa. Designed specifically for high-skill professionals, investors, startup founders, and executives in targeted industries—including tech, healthcare, and robotics—the Smart Visa streamlines the process of living and working in Thailand long-term. However, it comes with a unique set of documentation requirements that Australian applicants must prepare for carefully.
What is the Thailand Smart Visa?
Launched to accelerate Thailand’s transition to a knowledge-based economy, the Smart Visa targets sectors such as biotech, digital technology, robotics, and startups. The visa categories include Smart “T” for talent, Smart “I” for investors, Smart “E” for executives, and Smart “S” for startup entrepreneurs. It offers benefits like:
- No need for a separate work permit
- Up to four years’ visa validity
- Spouse and dependents allowed to work without separate permits
To qualify, applicants must meet role-specific criteria—such as salary thresholds or investment minimums—and present documentation to prove their credentials and business activities. This is where Australian applicants often encounter hurdles: the documents must be authenticated and, in many cases, attested by relevant Thai authorities.
Unique Documentation Requirements for the Smart Visa
Australian applicants must ensure their credentials are legalised according to Thailand’s immigration authorities’ expectations. The key documents typically required include:
- Educational Qualifications: Degrees and transcripts demonstrating relevant expertise must be authenticated to prove their validity.
- Employment Verification: Letters from employers, contracts, and proof of work experience must be submitted and verified.
- Company Incorporation Documents: For startup founders and investors, documents such as the company’s constitution, business registration certificates, and board resolutions must be legalised.
- Financial Statements and Investment Proof: Investors must provide notarised financial documents showing capital invested or assets held.
- Police Clearance Certificate: A National Police Certificate, legalised for use in Thailand, may be required to establish good character.
Since Thailand is not a party to The Hague Apostille Convention Abolishing the Requirement for Legalisation of Foreign Documents (Hague Apostille Convention), Australian documents require attestation rather than an Apostille. This process involves obtaining an authentication certificate from the Australian Department of Foreign Affairs and Trade (DFAT), followed by attestation from the Royal Thai Embassy in Canberra.

How Attestation Differs from Apostille for Thailand
It is important to distinguish between Apostille and attestation in this context. While Apostille applies to Hague Convention countries, Thailand falls outside this group. Therefore, Australian applicants must follow the attestation process, which is more involved and requires embassy legalisation.
A notary public in Australia can verify the authenticity of your original documents and issue a notarised copy accompanied by a Notarial Certificate. This step is often essential before submitting documents to DFAT and the Royal Thai Embassy for attestation.
