Hmmm I don’t introduce myself in Vietnamese. Typically my dad doesn’t for me since I don’t speak it. And I’ve only introduced myself in khmer a few times but it was very short. (I don’t speak it well either) However I have given introductions in English so I’ll speak about that! I feel like American greetings are very casual. Some people hug or give handshakes. Since I have a harder name than others, I came up with a fun way to help people pronounce my name correctly. “Chan” is like Jackie Chan and chaneryna like a ballerina. Things like that help break the ice and make people more comfortable to engage in a conversation with me. ( at least that's what I think). Instead of talking more about yourself, most people engage in small talk in America While in Japan introductions are very important and therefore pretty formal and straight to the point. ( from what I have observed) But Like Japanese in both Khmer and Vietnamese you have to be careful of the way you address someone....
