Patriotism is the word that describes a love or devotion to a person's own country. I'm looking for a similar word except one that describes this same feeling when it is not your own country you’re feeling this towards but rather another country that is not your own.
Generally, when one has excessive fondness for a country or culture that is not one's own, one would employ a specific term like any of the following:
- Anglophile - an admirer of Great Britain or England
- Americanophile - an admirer of the United States of America
- Germanophile - an admirer of Germany
- Francophile - an admirer of France
- Sinophile - an admirer of China
- Japanophile - an admirer of Japan
- Swedophile - an admirer of Sweden
- Philhellene - an admirer of Greece
There are many more words formed on analogy with these.
- attracted to that which is foreign, especially to foreign peoples, manners, or cultures.
Given that you asked for single word, that there does not appear to be a single-word solution, and that you used the tag "is-it-a-word", I'll venture a neologism: ceterapatriotism.
From your question:
Patriotism: love of a person's own country
From English-Latin dictionary and knowledge of Latin declensions:
Patria (f): country
Patriotism/love of a person's own country: amor patriae
Other (f): cetera
Another country: cetera patria
Love of another country, other than one's own: amor ceterae patriae
amor ceterae patriae --> ceterapatriotism
If you hate it, you hate it, but it at least answers the question.
Two of its meanings may apply, depending on what it is you have in mind.
1 a : the obligation of a feudal vassal to his liege lord
b (1) : the fidelity owed by a subject or citizen to a sovereign or government (2) : the obligation of an alien to the government under which the alien resides
2 : devotion or loyalty to a person, group, or cause
Interestingly (I think; and possibly evidence counter to my suggestion),
Although [the French Foreign Legion] is part of the French Military, it is the only unit of the military that does not swear allegiance to France, but to the Foreign Legion itself.
