Can I extend a Non-B visa after starting a business in Thailand without income or employees?

Dear Thai visa advice group members,

I would like to ask you for advice or help to resolve my problem.

In my home country, I got Non-B visa to conduct business in Thailand for 90 days. My plan was to extend this visa in Thailand for 1 year.

Last year I established a company but till now no income, no employees, just 2 mil. registered capital.

I got advice that I can obtain Non-B at my home country (conduct business) and come to Thailand and extend visa for 1 year based on my Thai company.

I have heard that visa requirements are not exactly specified and it will be enough to prove that I have a "working company" and it is up to immigration officer how he will consider my request. Like it depends on immigration office and some of them require proof of company income, office or 4 employees and some of them want to see only certification of the company (DBD) and it is enough.

Today I contacted agency and they said. I have to get work permit to apply for an extension of Non-B visa.

I really need to get WP and do all the steps in the company like VAT registration and 4 employees and after that, I will be able to apply for an extension of 1 year Non-B visa?

I will be glad for any advice. Thank you and have a nice day.
