Application for French citizenship is often interpreted as a renunciation of previous state allegiance unless a dual citizenship agreement exists between the two countries (for instance, this is the case with Switzerland: one can be both French and Swiss).
Taotlust omandada Prantsuse kodakondsus on sageli tõlgendatud loobumisena lojaalsusest eelmisele riigile, kui nende vahel pole topeltkodakondsuse lepingut (nagu Prantsusmaal on näiteks Šveitsiga).
