Hi! I have similar feeling about my adoption. I was also born in 1996 and was adopted by a French family. I am Vietnamese. I love my name: a Vietnamese first name and a Polish family name. People don’t know what to expect when seeing this name. Like you I still don’t know on which seat to sit. Should I go with the Vietnamese student association or the French alliances? Where do I belong. Unlike you, I kept in touch with my Vietnamese family and often visit them. I am actually writing from my Vietnamese relatives home in Singapore. I am going to live few months in Vietnam next month, I love the country. I also want to improve my language and get a professional level. I feel French in many other ways, my revolutionary character is definitely French. The last 5 years, I have been traveling around the world to understand who I was, what does family or friends means, where is home. Today a professor asked me “when are you going back home”, I answered “I am going back to France in April”. When people ask me “where are you from” I will not always answer the same question. In Mexico, people never believed me when I told them I was French, so I ended saying I was Vietnamese. Fun, no ?
Finally, I am a dual citizen, French Vietnamese, and a world citizen.
