Definicija: Gibanje oseb, ki se dogaja izven okvirov veljavnih zakonov države pošiljateljice, prejemnice ali tranzitne države. Jasne in splošne opredelitve nedovoljenih migracij ni.

S strani države pošiljateljice gre za nedovoljenost takrat, ko oseba prečka mednarodno mejo brez veljavnega potnega lista ali potovalnega dokumenta ali ne izpolnjuje upravnih zahtev za zapustitev države.
