What additional documents do I need for my DTV visa application as an Independent Freelancer in Thailand?

Hi everyone, I need URGENT help with my DTV visa application as an Independent Freelancer.

I just got an email asking for more documents, even though I already submitted most during the original application. Can you please guide me on these points:

1. Business License / GST – I don’t have a registered business, I work as a freelancer with monthly contracts. Should I submit my client’s LLC? Or what else can I provide?

2. Flights & Hotel – I only gave flight number + Agoda “pay later” bookings (which now expired today). Do they want an actual ticket + fresh booking?

3. Employment Contract/Certificate – I don’t have a formal certificate, only client contracts (already submitted). Should I add letterhead + client's sign as advised, or is there another way?

4. All Passport Pages – This I can submit.

From what I hear, Mumbai consulate looks for strong proof of regular income + ability to sustain yourself in Thailand.

Would really appreciate guidance from those who have gone through this 🙏

Thanks in advance!
