Aliens in the Men in Black universe are expected to act as hidden, law-abiding refugees, immigrants, or temporary residents who blend seamlessly into human society while following strict MIB protocols to maintain secrecy. They generally appear human or wear human disguises, often living mundane lives in New York City while pursuing, in many cases, peaceful integration. They are required to register with the MIB Immigration Center upon arrival and abide by intergalactic treaties, which prevent them from acting aggressively or revealing their extraterrestrial nature.
