The employee's work permit states "laborer" but the actual job involves standing and selling goods in front of the shop — the work permit must be amended, not the job itself. Exworker handles the submission of Form BT.22 to change or add job types in the migrant worker's work permit, covering both laborer → shop sales and vice versa.

This task doesn't involve many documents, but the pitfall lies in the pre-submission assessment: whether the shop has a commercial registration, how many more people the employer's income tax quota allows, and whether to choose "change" or "add" job types. We check these three points first, then prepare the documents and submit.

Does your case meet the conditions? — 30-second check

Can proceed immediately Shop has commercial registration + filed taxes last year

Prepare documents according to the list below immediately. Only need to check if the quota is not full.

Needs amendment first No commercial registration yet

The shop sales side must have commercial registration evidence or official documents related to commercial activities. We help check if it falls under an exemption or requires prior registration.

Different matter Want to move to a new employer

That is a change of employer, not BT.22 — See Change of Employer Services

Choose correctly before submission: "Change" or "Add" job type

In Form BT.22, only one option can be selected, and the outcomes are completely different.

Change job type Only the new job remains

The original job disappears from the work permit. Suitable for employees who fully transition to shop sales.

Add job type Can do both jobs

Retain the laborer job and add the shop sales job. Suitable for actual work where tasks are alternated — safer if the employee still needs to lift items.

We ask this question for every case "After changing, will the employee still lift items or manage stock?" If the answer is yes, and a "change" form is submitted, returning to lifting items will become working outside the permitted scope again — incurring submission fees twice due to ticking the wrong box.

Quota: How many migrant workers can be hired for shop sales

Applies only to shop sales jobs — laborer jobs do not have a hiring ratio specified.

Employer's status in the past tax year	Can hire
Started commercial activities / registered as a legal entity and has no income yet	1 person
Exempt from income tax	1 person
Paid income tax 1 – 50,000 Baht	3 people
Over 50,000 Baht — for every 50,000 Baht, 1 additional person can be hired	Not exceeding 10 people
10 people + hired 30 Thai nationals (for every 10 additional Thai nationals, 1 additional migrant worker can be hired)	Ceiling of 20 people

All-inclusive price, no hidden extras

The amount in the price box at the top of this page includes government fees and stamp duty. It is not merely a service fee to be added later.

Government feesApplication form fee 100 Baht and fees collected by the office, totaling approximately 400 Baht per person.

Stamp dutyPower of attorney 10 Baht per copy (if employer is a legal entity, 30 Baht rate applies; this difference will be shown separately during case review).

Why employers let us handle the process

Assess the case before submission to ensure documents and quota meet conditions, no need to gamble at the counter (approval authority rests with the registrar).
Calculate quota from actual tax evidence, not guesswork based on sales.
Choose "change" or "add" based on actual job duties, to avoid resubmission.
Can assist clients with multiple employees simultaneously, submitting as a batch.

Frequently Asked Questions

Does changing the job type extend the work permit's validity?

No, it does not. BT.22 is an amendment to the work permit's details, not a renewal. The expiry date remains the same, and renewal must still follow the schedule for its group.

Does the employee need to be present for submission?

If not present in person, a power of attorney is required from both the employer and the migrant worker, with stamp duty affixed at the correct rate. We prepare both documents.

How many days does it take?

The Department of Employment's document set does not specify the number of working days, and queues vary by area. We will inform you of the actual timeframe for the local office during the case review.

Can it be done without commercial registration?

The shop sales side must have commercial registration evidence or official documents related to commercial activities. There are groups exempt under commercial registration law, but they must genuinely meet the conditions. We can check this for you first.

Can the employee sell goods in front of the shop while waiting?

It is not advisable. Working outside the permitted job type carries liability for both the employer and the employee. The risk exists every day until it is amended.
