What are my options for obtaining a DTV visa for myself and my girlfriend in Vietnam without using my embassy?

Thanks everyone for the headsup! I'm planing to return to Lithuania in January and would leave for Thai in February directly, found out that we do have a Consulate who handles the DTV visas in Lithuania apparently. Though not sure - the webpage doesn't work, sent them an email. This one I'll figure out either way - as if I'm not obliged to be there in person, I could apply from Vietnam then in the worst case. Still much better, as heading to Denmark and "sitting" there 😉 Another question - do I have to show the last XXX monthly income to my company, or proof of 500 k Baht is enough on my bank account? I do have more there, but no stable income for now. Have also own company, but no operation this year, last year income was ~ 40 k. Do they require to show stable workflow (like contracts, invoices, company bank statements with money "movement" etc.) or will the proof of my personal bank account with 500+ k Baht be enough? (over a year in the account). THANKS!
