Immigration Act B.E. 2522 (1979), as amended
Governs visa categories, extensions of stay, residence notification and grounds of inadmissibility.
Central Thailand — Bangkok
Visas, work permits, residency and lawful status

Bangkok concentrates the courts, central government departments, embassies and most corporate head offices in Thailand. A legal matter arising in Bangkok therefore usually touches several authorities at once — the court with territorial jurisdiction, the Department of Business Development, the district land offices, the Immigration Bureau and the Department of Consular Affairs. Sequencing the steps correctly from the start saves far more time than correcting them later.
Legal advice and filings on the status of foreign nationals in Thailand — visa categories, extensions, work permits, 90-day reporting, and difficult cases such as overstay, refusal and appeals.
Jurisdiction and filing requirements should be confirmed for each matter, because practice and required attachments differ between offices.
| Court / authority | What it handles |
|---|---|
| Civil Court, Criminal Court and Bangkok municipal courts | Hear civil and criminal cases according to territorial jurisdiction in Bangkok |
| Central Labour Court | Dismissal, severance and employment-contract disputes |
| Central Administrative Court | Challenges to state orders and administrative action |
| Central Intellectual Property and International Trade Court | Trademark, copyright, patent and international trade cases |
| Central Bankruptcy Court | Bankruptcy and business rehabilitation |
| Legal Execution Department | Seizure, garnishment, auction and execution-stage mediation |
| Department of Business Development | Company registration and registered changes |
| Department of Consular Affairs, MFA | Legalisation of documents for overseas use |
| Immigration Bureau | Visas, extensions of stay and residence notification |
Extensions are usually decided within weeks; permanent residence and naturalisation take years.
Timeframes are indicative and depend on the court calendar and the authority handling the matter in Bangkok.
Summarised for general understanding only. The application of each provision depends on the facts of your case.

These are constructed examples used to explain procedure. They are not client matters, and no outcome is implied or guaranteed.
Situation: The applicant meets the amount but not the required seasoning period.
Usual approach: Verify seasoning rules and evidence format before the filing date and allow time for bank letters; document practice varies between immigration offices. (Hypothetical.)

It depends on the case type and territorial jurisdiction. General civil and criminal cases go to separate courts, while labour, administrative, IP and bankruptcy matters each have a specialised court. We verify jurisdiction from the parties’ domicile and the place of the events before filing.
Not every hearing. With a proper appointment of counsel and power of attorney, your lawyer can act for you in many steps, but hearings where you must testify require your attendance. We tell you in advance which dates are mandatory.
Always start from the receiving authority’s requirement — it dictates whether you need signature certification, translation, MFA legalisation and embassy endorsement, and in what order. For Thailand, the Apostille Convention enters into force on 28 February 2027; until then MFA and embassy legalisation continues to apply.
No. Working in Thailand requires a valid work permit, which is separate from the visa.
They generally need authentication in the issuing country, translation into Thai or English, and legalisation of the translation at the Department of Consular Affairs.
Thailand acceded to the Apostille Convention on 30 June 2026, entering into force on 28 February 2027. Until then, consular and embassy legalisation remains the route.
