What are the requirements for applying for a DTV visa for spouses and children in Vietnam?

# DTV (Application in Vietnam) for Spouses and Children Without a Permanent Residence

My wife has had a DTV visa for a few days now. However, we and our two children are planning to leave Germany permanently on March 2nd to live as digital nomads outside Germany. Therefore, *we will no longer have a permanent residence in Germany*. We are concerned about reapplying for the DTV visa for spouses in Frankfurt, as we only have two weeks left. The processing of my wife's DTV visa took a very long time, and additional certified documents from her company were requested. My questions are:

1) Is it sufficient to simply provide the address of the hotel where we will be staying in Vietnam once we arrive, and to select "Yes" to "Is your permanent address the same as your current address?"

2) Is a passport stamp and confirmation from the hotel, perhaps with photos taken in front of the hotel, sufficient? Or what did you use?

(I haven't found a definitive answer in the group yet, only that everyone mentions two addresses.)

Thank you in advance for your help!
