NON-B Visa @ Work Visa @ Business Visa

QUICK FACTS ON NON-B VISA

Did you Know?

  • “Non-B” stands for “Non-Immigrant Business” – it’s the essential visa for working legally in Thailand.
  • You can’t get a work permit without a valid Non-B Visa. It’s a legal requirement for employment or business ownership.
  • A typical Non-B Visa starts with a 90-day single entry, and can later be extended to a one-year visa with proper documentation.
  • You must apply outside of Thailand for the initial Non-B Visa (exceptions exist but are rare and case-specific).
  • A Thai employer, registered company, or BOI-certified business must sponsor your visa with official invitation letters and company papers.
  • Don’t forget: visa and work permit are separate processes—both are required, and both must be kept updated.
  • Common uses include employment, owning a Thai company, or business partnerships.
  • Using a tourist visa for work is illegal and may lead to deportation, fines, or blacklisting.

What Are the Requirements for a Non-B / Business / Work Visa?

We need to gather the correct documents.
Then, we help you prepare and review every paper, because each document must comply with Thai law and Immigration standards to avoid delays or rejections.

  • Valid Passport: First, check that your passport will remain valid for at least six months and has blank pages.
    We confirm your passport is ready for submission. An invalid passport will stop the process at the first step.
  • Job Offer or Company Documents: If you are an employee, you need an official job offer from a registered Thai company.
    If you are a business owner, then you need company registration and directorship papers. We check and format these documents for you. Correct paperwork is required for approval. For more on company registration, see Limited Company Setup.
  • Invitation or Sponsorship Letter: Your sponsoring company in Thailand must provide an official invitation letter.
    We help draft and review it, because Immigration needs clear evidence of sponsorship.
  • Company Registration Documents: We gather the company affidavit, VAT certificate, and financial statements.
    We ensure all documents match the current Thai Immigration requirements. Inconsistencies can cause delays.
    For more on business compliance, visit Business Licensing in Thailand.
  • Education & Experience Certificates: We collect your degree certificates, CV, or proof of your work history and review them.
    Immigration may request proof of relevant qualifications.
  • Application Form: We fill the official Non-B Visa application form for you.
    Then, we guide you step by step in completing it, to avoid mistakes on the form that can result in rejection.
    See official Non-B Visa info for more details.
  • Photos: We prepare the correct size and number of photographs and double-check. Incorrect photos are a common reason for delays.
  • Other Documents: We need to show your specific job or business situation.
    Then, we will advise on filing any additional documents, because every client’s case is unique and must meet all criteria before submission.
