Is there a time frame limitation for applying for a work permit after arriving in Thailand on a Non-B visa?

After arriving in Thailand on a Non-B visa, it's crucial to apply for your work permit promptly. While there's uncertainty about a specific time limit, some advice suggests needing to apply within about 15 days. It's essential to clarify this with your local Ministry of Labour since immigration rules may vary by location. Importantly, you cannot engage in any work activities without having your work permit issued, as there is no allowance for working without it.
