How can I apply for the DTV remote worker visa in Vietnam and what documents are required?

Hello everyone,

I want to apply for the DTV remote worker, in HCMC in Vietnam. Can anyone tell me if I should go there or somewhere else? Any experience on how long it takes or how hard it is to get everything approved? Do I need notary or apostille stamps for my documents? Obviously I have the money and income but I'm worried about other documents.

I have an official business registration and freelancer work contract from the Netherlands but I'm German myself. Any help and experience would help. Thanks in advance!
