Why is the Thai Embassy requesting my CEO's passport for my visa application?

Isn’t that a common practice?

I don’t know what stated on the letter that your boss signed, but whatever it is, your boss must bear responsibilities to what he signed on the letter if anything happened.

How can the Embassy prove that the person who signed the letter an actual person?

You boss could provide a copy of his passport and perhaps signed on the copy that it’s for only the visa purpose.

I’m curious if it’s possible to sue an embassy for the unlawful documents requests, and if someone went this way for the precedent at least, since request for disclosing third party personal information is not a lawful request

From our experience working with over 20 Thai embassies, the Thai Embassy in Hong Kong is one of the toughest places to get a DTV visa. A big reason is that many applicants have tried to use photoshopped financial documents or unverified work contracts, so the embassy is now extra strict.

If you’re planning to apply with the Muay Thai option, just having the basic documents isn’t enough. They might ask for proof that you’ve actually been training—like photos or videos with timestamps, or a training log showing at least six months of activity.

So if you’re applying in Hong Kong, be ready to submit more than the usual paperwork. Also, make sure to choose a legit Muay Thai school, preferably one that gives a refund if your visa gets rejected.

It’s clear the embassy is trying to filter out unreliable or insincere applications, so showing you’re serious about Muay Thai really helps.

Hk embassy is one of the worst. I have a friend that rejected there after few rounds of documents back and forth. I'm the end he went to another country to get his DTV with no issue.

Some posts have detailed the same request. Where did you apply? Apply elsewhere

Yep. I've heard it on this group. Not often though.

That’s crazy …

Try a different embassy

where did you apply from? when did they ask for that document?
