Visa Information
International students are responsible for maintaining valid immigration status throughout their studies in Thailand. Siam University can assist with university documents and institutional procedures, but final requirements and decisions are determined by the Royal Thai Government, Thai embassies and consulates, and the Immigration Bureau.
Immigration rules and document requirements may change. Students should confirm current requirements before applying, travelling, extending a visa, or leaving Thailand.
Before traveling to Thailand
Obtain the appropriate Non-Immigrant Education visa where required.
Use the official Thai E-Visa service or contact the relevant Royal Thai Embassy or Consulate.
Prepare the university acceptance and supporting documents requested for your application.
**The official Thai E-Visa site is operated by Thailand’s Ministry of Foreign Affairs and includes the online application process and studying-visa category.
**If you plan to travel outside of Thailand during your stay, a multi-entry visa can be purchased on arrival**
Before Arrival
Complete the Thailand Digital Arrival Card where required.
