    THAILAND VISA APPLICATION INFORMATION

  • Who Needs a Visa?
    Foreign nationals visiting Thailand may require a visa, depending on their nationality and purpose of travel. Citizens of certain countries (e.g., Singapore, Malaysia, and others under visa exemption agreements) may enter Thailand without a visa for short stays. Please check with the Royal Thai Embassy in your country for specific requirements.

    Recommended Application Time
    To avoid delays, applicants are advised to apply **at least 4 weeks** before their intended travel date.

    - One **recent passport-sized photo** (2x2 inches, white background, no glasses or headwear unless for religious reasons).
