Can I apply for a Non-B visa before my WP32 is ready in Thailand?

The user is starting work in Thailand on December 8 and inquired about the possibility of applying for a Non-B visa before obtaining the necessary WP32 documents. According to responses, the WP3 (work permit application document) is needed for the Non-B visa application. While the application for the Non-B visa can be initiated before the work permit is fully processed, the user cannot start work until the visa and work permit are secured.
