I can confirm that with the DTV proces from Embassy in Madrid, Spain. I sended company registration, as I'm the only shareholder, and explain my activities in Thailand: remote worker for my company, I added that in my free time I’m interested about to know Thailand country, the people, language and culture
In my experience, I sent a certified document from my bank, with my balance at that time, and this document does not say anything about whether the account is new or not.
I got DTV at Madrid’s Embassy, and I did not send my bank account movements, but only a certificate from the bank with my current balance. Embassy accepted that.
I’m in the same situation, and I got DTV past 5 september from Embassy in Madrid. They ask me for company registration(proof that
I’m the owner), and the last invoices of the company, I sended July invoices. They asked me for contracts with my customers, but I don’t have any contract, only software service at demand, I explained that and no other problem
