What QuickVisa does
QuickVisa provides document review, case preparation and procedural support for Non-B Visa. The final decision is made by the competent Thai authority.
What a Non-B visa is
Non-Immigrant Visa Category “B” is the Thai business/work entry category. People often call it Non-B or a “work visa”. Officially it is a business/work visa under MFA / Thai e-Visa “Work and Business Visas”.
It may be used to take employment with a Thai employer, conduct business activity, attend negotiations, teach where Category B applies, or work under a project or organisation that supports the application. The inviting company or employer must document the ground.
Non-B is not a Work Permit. Permission to work is a separate labour procedure. Holding Non-B does not by itself allow any job. The employer must not let a foreigner work without the required work authorisation. The two processes are handled by different authorities.
Service process
Initial case review → document checklist → document verification → application preparation → submission/appointment support where applicable → status follow-up.
What we need from the client
The exact checklist is case-specific. We first verify passport/immigration status, the legal basis of the application and supporting evidence required by the responsible authority.
What the client needs for Non-B
The list below is the official-source baseline. The exact checklist depends on category, nationality, place of filing and responsible authority.
- Passport/travel document valid for at least 6 months.
- Visa application information and recent photograph.
- Financial evidence under the applicable checklist.
- For employment: employer documents and Ministry of Labour approval/letter where required; MFA references the prospective-employer WP3 procedure.

What the Non-B Visa Is Used For
The Non-Immigrant B route is used for eligible business, employment, investment or professional activities connected with Thailand. It is commonly considered by employees of Thai companies, business visitors, company founders and applicants whose Thai organisation can provide the required supporting documents.
Typical use cases
An employer or Thai business may need to provide an invitation, employment details, company papers and other evidence. A Non-B visa and a Work Permit are separate matters: holding a visa does not automatically authorise local work, and the work authorisation must be arranged through the relevant process.
Before applying
The documents and sequence depend on the activity, employer, nationality and place of application. Review the official Thai e-Visa portal and the Non-B FAQ before submitting documents.
