Which type of visa should a foreigner married to a Thai apply for when getting a job in Thailand: Non-B or Non-O?

I am have been doing marriage visas for the past 2 years.. It's a real pain. If the job will do the visa stuff for him, let them.

I think the job company have to apply Non B visa for him + work permit.

But if you can apply Non O for him by marriage is another choice but you have to prepare your documents.

Your spouse can apply for a work permit with either type of visa.

A non-B allows work with a work permit, and a non-O based on marriage to a Thai allows work with a work permit.

You'll still need to meet the requirements for a non-O extension based on marriage, primarily the 400,000 baht in a bank account or 40,000 baht per month. If your spouse's salary is 40,000 baht or higher, they can use this salary as proof of income for the extension.

Please note: Many workplaces do not like an employee to use the non-O visa based on marriage to a Thai. Though it's less paperwork for the employer, it also means that this employer cannot use the threat of firing the employee and them being forced to leave Thailand immediately. Employers do not like to lose this power over the employee, so they may argue against your spouse using this method. If they do, you now know what kind of tactics this employers likes to use and may want to take that into account on if this is a good job or not.
