Work permit vs business visa: what each one covers
These are two separate authorisations, issued by two different agencies, and holding one without the other is a common and expensive mistake.
Side-by-side comparison
Point
Non-B business visa
Work permit
Issued by
Thai embassy/consulate or Immigration
Department of Employment
Permits
Entry and stay
Performing work lawfully
Company evidence
Affidavit, shareholder list, VAT registration
Same, plus financial statements and staff ratio
Personal documents
Passport, photos, employment letter
Degree and experience certificates, medical certificate
Certification needed
Foreign documents legalised
Foreign degrees translated and certified
How to choose
Sequence matters: obtain the Non-B first, then file the work permit within the permitted stay, then extend the visa on the strength of the permit. Foreign degrees and experience letters must be notarised and legalised in the issuing country before they are translated here, so start them early — that step is the usual delay.
Frequently asked questions
Can I work while the permit is pending?
No. Work may only begin once the permit is issued.
Does a digital nomad need a work permit?
It depends on where the work is performed and for whom; take advice before relying on a visa alone.
