In many Angel Island Novels, you'll find main characters like a father figure who has left his homeland to seek better economic opportunities for his family.

Another common type of main character might be a political refugee who is fleeing persecution in their home country and has to endure the long and arduous stay at Angel Island.
The main characters in the Angel Island Novel can vary widely. Some novels may focus on the immigration officers as main characters to show their side of the story, but more often it's the immigrants. For example, there could be a group of Filipino laborers who are coming to work in the United States. They are full of anticipation at the start of their journey, but as they reach Angel Island, they face various challenges like language barriers, cultural misunderstandings, and the strict immigration procedures. Their stories of perseverance and the relationships they form with other immigrants while on Angel Island can form the core of the novel.
