We have been granted our 475 visa but have recently had a baby who we are now adding on via a subsequent entrant 1276 application. Has anyone else been through this process?

We have got to the end of the form and it asks for main applicant & primary applicant signatures. Do we need to sign any of these or are they referring to the baby therefore it doesn't need a signature?

And does anyone know how long this application takes?

Many thanks Jacqui
