Work Permits & BOI: documents, steps and pitfalls

Documents to prepare

• Company affidavit and latest financial statements
• Employment contract stating position and scope
• Certified degrees and experience letters
• Medical certificate in the prescribed form
• A valid Non-Immigrant visa

Step-by-step process

1. 1

   Case assessment: define the end purpose and confirm that Foreign work authorisation through both the standard and BOI channels is what the receiving party actually requires.

2. 2

   Collect and pre-check every document so names, dates and spelling match before filing with Department of Employment and the Board of Investment.

3. 3

   Prepare translations or supporting papers in the prescribed format, then have a second reviewer verify them.

4. 4

   File with Department of Employment and the Board of Investment through the channel currently open, keeping proof of every submission.

5. 5

   Track status, answer officer queries and correct documents immediately if anything is challenged.

6. 6

   Collect the result, verify it before forwarding, and archive a complete set for future reference.

Cautions and common mistakes

• Thai-to-foreign staff ratios and capital rules differ per channel — verify with the authority
• The permitted scope not matching the work actually performed
• Foreign qualifications not yet legalised
