This person might already have a network in America and could introduce Harry to important people. Also, there could be some reclusive magical scholars in America who, out of curiosity about Harry's powers and his role in the UK, decide to help him. They could teach him new magical skills that are specific to the American wizarding world.
His friends from Hogwarts, like Ron and Hermione, are likely to help. Ron could bring his family's practical knowledge of wizarding homes and Hermione would contribute with her extensive research skills.
Well, in fanfiction, Neville Longbottom could be one of the visitors. He and Harry could exchange gardening tips as they explore the manor's gardens. Additionally, Dumbledore's portrait might be magically transported to Potter Manor, and he could offer his wisdom and guidance to Harry as he lives in the manor. And of course, Hagrid might come with some magical creatures to show Harry, adding more excitement to the manor.
Perhaps a long - lost relative of the Potter family who feels they were unjustly excluded from inheriting the manor.

As he delves deeper into the manor, he discovers rooms that hold memories of his ancestors. There might be a room dedicated to his parents, where he can see their early years through enchanted memories. This discovery could strengthen his connection to his family and give him a new sense of identity within the wizarding world.
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.

If Harry was raised at Potter Manor in fanfiction, it would change a great deal. He could have a more stable support system.

This would make him more confident and knowledgeable when he enters Hogwarts, and his relationships with his classmates might be different as he wouldn't have the same insecurities.
