, you can apply on eVisa system by yourself through consulate in US using your US address

@Albert ********

, OP is talking about his mother. DTV dependent is not available to a parent, it's only for a spouse and children.

It depends on the embassy whether they require applicants for DTV dependent to have financial proof for each.

Q. Are dependent visas still offered for Ed visa holders?

-> No. Non-O dependent is not available if the main foreigner is on Non-ED for studying at private schools, such as language schools.

Non-O dependent is applicable on Non-ED (not only Non-ED plus) as well, but only for those studying international schools (children), university for degrees, or higher.

Q. if a parent comes to do a year long language course, can they have dependent wife and children (not yet school age) ride on their visa?

-> No, they can't.

Q. will immigration accept the transaction date of 26th ?

-> Maybe not. But no downside to try early. Some offices might accept your documents 1 or 2 days with additional conditions.

You have to have funds in a bank account for the "past" two months, so you go to the local immigration office on the 27th. There is still a possibility that they won't accept your application until the 28th, depending on how the record shows on bank transactions.

Q. does immigration require updated photos each extension ?

-> That depends on your local office. You are supposed to provide new photos for the application to show your marriage is de facto and de jure.

It'd vary by office how strict they are about photos. Some are not, and some check comparing previous photos.

There were reposts that new photos weren't accepted because happened to wear similar clothes as previous photos in some province. While others in other provinces have no problem using the same photos as before.

@Col *******

, then you want to bring your passport and policy. Show the visa sticker page to the officer at passport control upon entering Thailand.

@Col *******

, you can bounce at a land border, by air, or so-called sea border.

Bring printed Non-OA (if eVisa) and a new insurance policy in hand to enter Thailand for another year. Make sure to check the entry stamp before you leave passport control that you are stamped in for 365 days (or insurance validity) with "Non-OA" in the "visa class" field on the entry stamp.

Savannakhet will be on eVisa as well, same schedule, same conditions as Vientiane.

@Andrew ********

, as I wrote, IF the visa ITSELF is multiple entry, it would work in that way.

@Andrew ********

, No, Non-O visa based on raising a Thai child is issued as only single entry visa. And extensions have no entries built in. When you are on an extension, you need a re-entry permit to travel out of Thailand to keep the current stamp valid. Entry stamp from re-entry permit is the same as the current extension. Re-entry permit wouldn't add any day after expiry of the current stamp.

@Andrew ********

, if multiple entry visa, the concept is the same. But visa validity, length of entry stamp, and some other conditions are different depending on the type of visa.
