the police order states 40,000 income is required . . . the OP obviously wants to get the 1-year extension without own money, and the agent asks for 60,000 THB service fee (to bribe the Immigration)

@Paul ******

well, the income requirement for a marriage extension is a minimum of 40,000 THB, not 60,000. However for this he needs the income affidavit of his embassy (only if his embassy issues it) , or a bank statement of 12 consecutive months of money transfers coming in onto his Thai bank account from abroad

@Shandy *******

that's what I recommended. She doesn't have an entry stamp in her passport, so no proof that she currently is inside Germany. However, the AirBnB receipt plus her German passport will suffice. You are not required to be resident of the country where you apply for the DTV, and definitely also not in Germany. . . . that embassy text refers to other visa categories

@Shandy *******

the German ID card got the resident adress on the back side. She says her German ID card is blank. The passport doesn't have an adress in it

@Dany *******

exactly. The wording on the website of the Thai Embassy Berlin she posted, is misleading. She does not need to be resident in the country where she applies for the DTV. The only problem is, as a German passport holder, she does not receive an entry stamp at the border when she enters Thailand. When you apply in Vietnam or Cambodia, you just upload that entry stamp as proof of being inside the country where you apply. Her only proof that she is staying inside Germany as a tourist, would be that AirBnB bill. Taking up "real" residency in Germany is much more complicated and would open a whole can of worms!

@Jeannine-Susann ********

you could try, use your German passport and your AirBnB bill as the proof that you have entered the country and apply from there. You do NOT need to be a resident of the country where you apply, for a DTV application. The requirement for a residency on the website of the Thai Embassy is formally wrong! . . . . . . . . This will become apparent to you once you start the process of E-visa application . . . . . . Just remember: You can apply for the DTV in every neighbour country of Thailand, and you do not have to be "resident" in order to apply for the DTV. . . . . . . . . . . . . .Even in Germany, there are only a few visa classes that need proof of residency. A turkish citizen on a tourist visa theoretically could apply by the Berlin Thai embassy for a 90-days Non-Imm-O Retirement Visa, if he fulfills the financial requirements

@Jeannine-Susann ********

you are receiving a lot of unrelated info here, as most people are not common with the special laws and regulations in Germany regarding residency, proofs of address, bank accounts et cetera. Mainly Dany Nomads' advice is completely useless as he is not aware that you canot fulfill the requirements asked on the Berlin embassy website, no matter how you turn or twist it

@Jeannine-Susann ********

applying in Vietnam or Vientiane/Laos is the easier option, as you can prove by the stamp in your passport that you have entered their country. However in Vientiane, AFAIK the embassy requires a proof that you had a minimum of 500,000 THB in your account for the last three months

@Ralph ******

a foreigner first needs a Non-Imm-B visa, in order to apply for a work permit. So, in order to change the visa or receive a Non-Imm-B visa, a foreigners needs to invalidate his existing visa or stay permit, which in most cases is done by exiting Thailand without a re-entry permit

@Bryce ******

I'd say it is not such a good answer, most of all the last sentence doesn't make any sense . . . . . . .as you can't work on ANY of the visas Ralph listed - you won't even get a work permit issued
