- Creator's Favorite Episode: Matt Groening named this as one of his ten favourite episodes.
- Unintentional Period Piece: Apu lamenting Tom Cruise and Nicole Kidman staring at him with their dead eyes dates the episode, as the couple has long since broken up (2001, to be exact).
- Working Title: The episode was originally called "The Anti-Immigrant Song", a play on Led Zeppelin's "Immigrant Song".
- Write What You Know: Apu studying computer science is based on David X. Cohen's own academic background, where he met and became friends with Indian people in the department. Similarly, the scene where Apu does an in-depth explanation of what caused the American Civil War, only for the test taker to respond with "just say slavery", is something that actually happened to a friend of Cohen when she got her citizenship test taken.
