What should I do if the Italian family reunion approval is not enough?

Italy's approval for family reunion is not enough to apply to the local police station for family reunion. Foreign immigrants who have lived in Italy for a long time or for at least one year (including employment residence, independent work residence, asylum, study, family reasons, religious reasons, humanitarian reasons, auxiliary protection, etc.) can apply to the local police station for family reunion, which will be approved by the police station and will be valid for 6 months from the date of approval. If the materials are submitted after the deadline, the visa center will not accept the application.
