I think when one lives “abroad,” there is some upside-down U-shaped curve about feelings towards one’s home country (or passport-holding country).
Before you leave the national borders of the land that you grew up in, you don’t consider that you could be from another country. “Where are you from?” is usually assumed to be the state or province that one is from.
Once you set foot outside, whether to study, live, or tour, at first, you feel proud to answer I’m _________ or I’m from _________ and state your nationality or home country with pride. It’s almost as if it is in these instances that you yourself become explicitly aware of your country of loyalty. In particular if you don’t look like what people usually assume to be the look of a person of such nationality–usually because of your race–then, in these instances you may feel you have to defend your legitimacy with an overcompensating force and each time someone accepts what you say without further questions is a triumph. It’s something that can warm your blood and make you feel more patriotism then you ever felt because sometimes in your own country you may have hunches about some portion of the population simply assuming you are not local and does not bother to inquire.
But hey, after living abroad for over a year, everything begins to change. The concept of being a citizen of a country seems increasingly arbitrary and elusive. “Where are you from?” is now answered with increasing nonchalance and you no longer give two shits about whether people question it or not. You are not bothered by a further explanation if need be. Everything goes. Without your overly confident answers, people feel free enough to even use the term “passport country” as a follow-up clarification. What does it matter, really, on a human level?
I am a citizen of the world. I believe in global interests. I don’t think war is ever the answer. Why do we draw boundaries?
