Non-Immigrant B visa for work in Thailand

It depends on the authorities and on your documents. The steps are our employer review, the visa at the Thai embassy, the work permit in Thailand, then the visa extension. Most of the variation comes from the embassy you apply at. For employers with BOI promotion, the process goes through the One Stop Service Center instead.

No. Working without a work permit is illegal under the Royal Decree on Managing the Employment of Foreign Workers B.E. 2560 (2017), as amended. Penalties include fines for you and your employer, deportation, and a ban on re-entry. Unpaid work for a Thai company can also count as work. Some short business activities, such as attending meetings, do not need a permit, and urgent work of up to 15 days can be done after notifying the Department of Employment.

The usual reasons are incomplete employer documents, too little capital or too few Thai employees at the employer, an inconsistent applicant profile, or a travel history that suggests overstay risk. Our review before filing catches these issues. Applying again after a rejection means new fees and more time.

Yes. A Non-B covers only the employee. Spouses and children usually apply for Non-Immigrant O (Non-O) dependent visas, which we prepare at the same time. Their applications rely on the main visa holder's documents and are processed alongside.

The Non-IB is the version for employees of BOI-promoted companies. It is processed through the BOI's One Stop Service Center, which is faster, and the capital and Thai headcount rules usually do not apply to BOI-approved positions. See our Non-Immigrant IB visa page.

Yes, but it takes several steps: the old work permit is canceled, the new employer applies for a new one, and your visa may need to be changed or extended. Timing depends on the authorities.

Once your permission to stay ends, every extra day is an overstay: THB 500 per day, up to THB 20,000, with a risk of detention, deportation, and a ban on re-entry. Use the first 90 days to get the work permit and file the one-year extension before that date.

For new hires, almost always. The bundle costs THB 35,000, less than separate filings (visa from THB 25,000 plus work permit THB 20,000), and we sequence the two correctly. The stand-alone visa usually makes sense only when you already hold a valid work permit from a previous Thai role.
