Can I use corporate funds to qualify for a Thai DTV visa for myself and my girlfriend?

DTV Workcation question – corporate funds + sponsoring girlfriend

I’m a Canadian citizen applying for the DTV through Vancouver. I own 50% of a Canadian corporation and work remotely.

For my application, I submitted:

* 3 months of corporate bank statements well above 500,000 THB

* corporate sponsorship letter

* proof I’m a shareholder/director

* incorporation documents

* professional portfolio

The consulate came back asking for 3 consecutive months of PERSONAL bank statements showing 500,000 THB+ at the end of each month.

Most of my funds are kept inside the corporation, not my personal account.

Has anyone successfully had a Thai consulate accept a company bank account + corporate sponsorship letter instead of personal statements?

Also, my girlfriend is a Mexican citizen living legally in Canada on a study permit. She does not personally have enough funds to meet the DTV financial requirement.

Is there any way for my corporation to financially sponsor her DTV as well, using the same business bank account and a corporate sponsorship letter, even though we are not married?

Also wondering:

* Can she apply from Canada while on a study permit, or does she need to apply from Mexico?

* Has anyone successfully used a company as financial sponsor for a girlfriend/partner’s DTV?

* Does the sponsor need to be a spouse/family member, or can it be a corporation?

Looking for recent experiences, especially with Vancouver or Mexico DTV applications.
