It is a good but stupid question, hehe
It depends on specific person's integrity.
Do not focus on his citizenship, pleas focus on his or her personality and integrity.
If a person loves his country, his people and his culture, also with cognitive empathy, he will respect other people's culture, history and love those people.
Also you should talk about specific scenario, when it comes to love, I think male guys will prefer sex, haha, so they are not trustworthy.
