Can I start working in Thailand while my work permit is being processed?

In Thailand, it's required by law to have a work permit before starting work. However, some experiences shared indicate that it's common for employees to begin working while their work permits are being finalized. Typically, companies will apply for the work permit while you are still abroad. Once approved, you can then apply for a Non Immigrant B visa. Upon entering Thailand, you can pick up your work permit and officially start working. There’s a noted lack of an official grace period, but informal practices may allow for some leeway during the paperwork process.
