I posted about my experience in early October.
Overall it was a decent experience. Mine took two days because they wanted a supervisor to review my documents that afternoon before they took the fee. And I had to do a little interview to explain some things.
My company in USA is a C-Corp and I provided EIN doc, Articles of Incorporation, etc but no city business license. Had to walk them through that as they seem to prefer city biz license and weren't familiar with the state and federal level documents.
Bank docs were easy. We looked up the exchange rate and wrote the Thai baht equivalent next to the USD balances.
They did look at the bank statements to see income coming in. I wrote a letter from my company to the embassy about my work and allowed to work remotely
I had an METV when I went. They asked if I flew to Taipei specifically to apply for the DTV and I said yes.
One note - the printing services at FamilyMart and 7-11 are great! Very convenient and inexpensive
