What are the options for obtaining DTV visas for family members of a U.S. citizen entering Thailand?

Hello, we’re 4 Americans for the DTV Visa. I expect to get approved for my DTV via eVisa process through the Los Angeles Consulate. I made the mistake of not realizing the eVisa process is 15 business days and don’t have enough time in the States to apply for my Spouse and dependents before we head to Thailand. Therefore we need to pivot.

Now the plan is that I will enter with my DTV. It looks like we need to do an eVisa as a tourist visa for each of them before they arrive in Thailand. Can anyone confirm this? I’ve heard it just rolled out this month. I assume I will also need to show a flight of them leaving Thailand within 60 days on the day we enter.

We’re now looking at going somewhere in SE Asia to apply for their DTVs in that 60 day window. So far we’re looking at the consulates below. I know you need to book an appointment for several of them.

* Phnom Penh, Cambodia

* Vientiane, Laos

* Kuala Lumpur, Malaysia

Does anyone have a recommendation on what Consulate we should go to and if there is anything crucial we’re missing? Thanks in advance.
