never happens cuz who and how will take selfies in immigration web computer system on the border.

Technically you can enter Thailand under 60 days stamp and it would not effect granting DTV. After granting DTV you will have to leave Thailand and re-enter with new DTV visa. Possible you will be not effected at all if lucky enough.

But generally it's still will be breaking rules. And if immigration officers will pay attention very well after during reentry or extensions it would be visible by dates that you were in Thailand when DTV was granted everyone would be able to see it by visa stamps. Generally it's not a big problem but can raise questions every time from immigration officers.

Anyway I would not recommend it to do to anyone. But if you have no choice under emergency situation...

I had very unpleasant experiences, when I had my NON B from Embassy with sticker visa in my passport, but immigration officer with them smart *computer* system, stamped me visa exemption for 60 days, instead of activation of my NON B. And when I came to immigration office they told me it is the best to go out and re-enter again with my Non B or trying to find that immigration officer in the airport and please him to fix this mistake that he made. So I did easy way later I just re-enter again with my NON B, but important to do it till the entry in the visa sticker is still valid.

Thai embassy and Thai immigration

They don't have one system.

Thailand's Immigration Bureau and the Ministry of Foreign Affairs (MFA) are different entities with distinct functions:

1. **Thailand Immigration Bureau**: This entity is part of the Royal Thai Police and is responsible for regulating the entry, stay, and exit of foreigners in Thailand. It handles visa applications, work permits, and visa extensions for foreigners already within the country.

2. **Ministry of Foreign Affairs (MFA)**: The MFA is a government body responsible for Thailand's diplomatic relations and foreign affairs. It oversees Thai embassies and consulates abroad, where visa applications and related services for entering Thailand are processed.

In summary, the Immigration Bureau deals with immigration matters inside Thailand, while the MFA manages international relations, including visa issuance through its overseas missions.

but if there Evisa and not any stamp about second visa in passport, hard to know for anybody about this secret.

But basically correct rules is rules it's not allowed.

But I saw some cases already happened especially with DTV EVisa.

@Ray ****

Offline work or business inside Thailand without Work permit is still illegal.

Only work outside of Thailand online is ok for DTV.

If you are in Thailand already with visa free or NON B got work permit processing in immigration, and you just got EVisa DTV previously from Thai Embassy outside of Thailand, but did not enter with this visa into Thailand yet, but already got work permit so you can try entering Thailand when your work permit expires if DTV would still be valid in future.
