I have been through the visa application and expected to get my visa this week having been through medical and police checks in June.
Just found out immigration will not further process my visa till my discharge date, Jan 04.
I finish (because of leave, terminal leave, resettlement etc) in three weeks.
Does anyone know any way of speeding the visa application as I need to arrive in Oz by March 14th because of medicals etc.
