No, you cannot obtain a Thailand work visa without a job offer, as it is one of the primary requirements for qualifying for a Thai work visa. The work permit is directly linked to the company and the job role offered in Thailand, as the Thai employer is responsible for initiating the process and submitting documents such as financial statements, an official approval letter, and a business registration to support your work visa application. To apply for a work visa in Thailand, you must have a job offer in hand.
