Dunki movie is not the first movie about immigration without documentation. The Punjabi movie "Aaja Mexico Chaliye" (2022), which follows a group of young people as they attempt to enter the nation illegally, has a plotline quite similar to this one.
Dunki movie is not a direct copy of Aaja Mexico Chaliye. While both films deal with the topic of illegal migration, there are significant differences in their plots, settings, and characters.
