It is always good to structure your presentation of evidences through powerful submissions addressing each concern of the officer. This does not only need a good understanding of migration law and Departmental policies but also a strategic approach.
We at Migration Centre of Australia specialise in writing submissions to the Department of Home Affairs in response to RFIs and have helped several clients in getting approvals of their applications from (DoHA). If you are in this situation and need help, call us on +61 2 46261002 or Contact Us to speak to our migration specialists.
