It demonstrates how the rhetoric and possible deportation affects Apu Nahasapeemapetilon, a character revealed in this episode to be in the United States on an expired visa. The episode presents the issue with a decidedly pro-immigrant stance. The season 20 episode "Coming to Homerica" revisits the immigration debate, with the plot following the residents of Springfield enlisting in a border patrol group and building a border barrier to deny entry to a Norwegian-American community.

The episode is critical of the Chinese government, and it makes multiple references to the 1989 Tiananmen Square protests and massacre. These include a reference to Mao Zedong as "a little angel that killed 50 million
