They might introduce Harry to how they blend in with the American Muggle society while still practicing magic. And he could also meet some American pure - blood families who have their own long - standing traditions and rivalries within the American magical community.
Harry could meet students from Ilvermorny. They would have different personalities and magical abilities compared to Hogwarts students.

Additionally, he could come across American Aurors who have their own methods of dealing with dark wizards.
There's a chance he meets some magical creatures that can talk in the American wilderness. For example, he might encounter a Sasquatch that has a deep understanding of the ancient magic in America. They could form an unlikely friendship and the Sasquatch could help Harry in his journey to adapt to the new magical environment.
One possibility is that Harry is simply on a holiday in America. He visits famous American wizarding places like Ilvermorny School of Witchcraft and Wizardry. There, he meets new friends and has adventures. He could even participate in an American - style magical sport tournament that is different from Quidditch.
Harry might meet some American wizarding families that have long - standing traditions different from the pure - blood families in the UK.

He could also meet American Muggle - born wizards who have their own unique stories of discovering magic in a different cultural context compared to what he's used to.
He could meet American witches and wizards. Maybe a young and adventurous American wizard who shows him around the American magical world.
He could meet American wizards and witches. Maybe there's a young and enthusiastic wizard who becomes his guide in America, showing him around the American magical communities.

In the fanfic, Harry Potter could meet the new generation of students. They would be in awe of him. He might also encounter some of the ghosts, like Nearly Headless Nick, who would surely have some interesting stories to share since Harry left. And there's a good chance he'll meet the caretaker, who would probably give him a hard time about coming back and causing a stir. Moreover, he could cross paths with some of the older students who idolize him and want to learn from his experiences.
Well, perhaps Dudley would apologize for all the years of bullying. He might have a newfound respect for Harry after everything Harry has accomplished. Harry could then share some of his magical experiences in a more light - hearted way, like showing Dudley some harmless magic tricks.
He could meet the castle guards. They might be suspicious of him at first but then become friendly as they realize he has no bad intentions.
Perhaps he'll meet a mysterious old wizard who lives in a secluded temple in the mountains. This wizard could be a master of ancient Japanese magic and could teach Harry about the spiritual side of magic that is deeply ingrained in Japanese culture. Harry might also meet a group of young Japanese witches who are training to become magical healers. They could share their knowledge of Japanese magical plants and how to use them for healing, which would be very different from the healing methods Harry learned at Hogwarts.
