Where do the loyalties of naturalized US (and Canadian) citizens truely lie? I feel that this was less of an issue until the US began allowing dual citizenships i.e. you no longer have to renounce citizenship from your country of origin in order to become a US citizen / you can become a citizen of another country and still be a US citizen. On the surface, you'd expect this to be simple; these individuals would be most loyal to the US... As a naturalized US citizen of Chinese descent, I've had some interesting conversations with other naturalized US citizens of Chinese descent that would show that it's more complicated than that.
I'm not sure how, but the topic of "what would happen if China and the US ever declared war on each other?" came up. To my surprise, the other naturalized Chinese Americans told me that they would be conflicted as to who they would support. For context, these are educated people with post-grad degrees from places like Berkeley with occupations to match. They also seem completely naturalized with accents that would fool people into thinking they were born and raised here. The kicker is that neither person was born or raised in China but each grew up in some Southeast Asian country, yet they're essentially comtemplating treason solely due to their race. I found it strange. Since what I have is just anecdotal, I'm guessing (and hoping) that most naturalized US citizens are way more loyal than that and I feel that Chinese Americans born and raised in the US don't have this issue at all. Still I have a feeling that this is probably only going to get worse when you have stuff like birth tourism happening i.e. You get US citizens who spend most of their lives in a foreign country resulting in loyalties to that foreign country

To be fair, China isn't the only country related to this issue. I could be wrong but the US probably has the same problem with dual citizenships involving Russia, Israel, Turkey, or any other country that isn't 100% aligned with US interests
Of course, this has a fix. Just don't allow dual citizenships in the US. Force people to choose.
