I don't understand what you are asking. E-visa doesn't change anything about applying for a visa except that it's online. You still must apply through the Thai embassy that services where you are physically at. Bob asked a question about applying through the Thai embassy in Phnom Penh while he is physically in Cambodia, which is how you are required to do it. You cannot apply through a US Thai embassy unless you are in the US. When you start the application it asks you where you are at, and if you don't put that you are in the US it will not let you proceed.
