Why the extension ends with the job
A Non-Immigrant B extension granted for employment is tied to the specific employer that supported it. Once that employer reports the termination, the reason for your permission to stay no longer exists. Immigration offices commonly stamp a short permission period, often around seven days, so you can leave or regularise your status. Practice varies by office.
What your employer must do
- Notify the Department of Employment of the end of employment within the legal time limit and return or cancel the work permit.
- Inform immigration so the related extension of stay can be cancelled.
- Provide documents you may need later, such as an employment certificate and tax withholding certificate.

Your options
Each option depends on timing and documents being ready before the old extension is cancelled.
- A new employer files for a new work permit and supports a new extension; gaps between jobs are the main risk.
- A change of visa type inside Thailand where your circumstances fit, for example marriage to a Thai national or retirement age and funds.
- Applying from abroad, such as a DTV for remote work for clients outside Thailand, if you will not work for a Thai employer. Since 31 August 2026 (00:00 Thailand time), every DTV applicant must provide proof of permanent residence or nationality in the country of the embassy or consulate where they apply, replacing proof of current location, plus a police clearance certificate issued within 6 months of submission. Dependants under 16 may use the main applicant’s certificate. A visitor stay alone does not qualify you to apply at a regional post. Applications submitted before that date follow the old rules.
- Departure before the permission period expires, avoiding any overstay.
Common mistakes
Continuing to work for a new company before its work permit is issued, letting the short permission period lapse, and assuming the old employer has filed the cancellation when it has not. Each can lead to fines, refusal of the next application or an overstay record. For Non-BOI Non-B cancellations since mid-July 2026, officers at the Thailand Investment and Expat Services Center ask employers to supply a list of all expatriate employees and copies of their Digital Work Permits as an administrative practice, not a formal published rule.
