Just got the DTV in Manila! I submitted all the requested documents through the E Visa (I own my own business and was able to show bank statements from the business) and they requested details on my business and services, paperwork showing I founded and own the business, and the business license. I was staying here for a couple weeks and just used my hotel booking as proof of location and it was approved within a week.
So just putting it out there that Manila is a great option for applying!
