Hello. I'm a US citizen, but currently in Thailand. My bank statements and proof of address are in the US. As I was looking at the DTV application, it's asking me to apply thru the US Los Angeles office. But since I'm in Thailand already now, I was planning to go to Cambodia and apply through the website there. But do I need to apply through a Cambodian office and provide proof of address in Cambodia? Or can I still apply thru the USA, since all of my documents that I submit will have my USA address?
