It depends on the embassy she is applying from. Some may require double the amount.

Many apply 2nd time around by themselves and get approved. A few three times. It is good it worked out for you via an agent.

You should check your local Thai Embassy website for the application process. There are SP courses with Thai language as part of the course. Full time Thai language comes under Education visa so it is not really issued via DTV. If you extend your DTV at immigration you need to show course renewal docs if the course has ended. No current requirement to do so with a border hop. How long it takes depends on where you apply.

Anonymous participant With Wise you can pay rent and bills

. Visa fees must be paid in cash (Thai Baht) at the Consular Section (15 Bourichan Road, Ban Phonesinuan, Sisattanak District, Vientiane Capital)

Anonymous participant 173 There are many areas of Thailand where 1300 quid is above barely surviving.

You can get a DTV via rental property management. You need to show how you manage the business online. There is no minimum income requirement. You can find several posts in the threads from such DTVERS.

There are several posts from Manilla applicants in the threads. It is ok to transfer from a Time Deposit to a personal savings account. You need to check with Manilla if they have a seasoning requirement before applying

I used such a letter to get my DTV, Inc permission to work In Thailand via the DTV.

Anonymous participant I would just use my name applying as a freelancer. Applying with a business name will likely lead to a business registration request. Laos, Vietnam or Indonesia are great options.
