Family Reunion Visa with Kids

The embassy just send an email to us today that family reunion visa application for the kids has been forwarded to the immigration office after close to 6 weeks of depositing the visa application at TLS. Please does anyone know how long it will take for the visa to be approved.  Thanks for your assistance

All applications differ so it may take a short time or a long time.

Depends too on how busy the immigration office is.
