Travel overseas will not affect any application that you have lodged with us.  However you should liaise with the registry before any travel arrangements are made in order to establish whether or not your hearing or a decision is imminent.  You should also contact the Department of Immigration and Border Protection or the Department of Home Affairs if you have any questions about your authority to travel or re-enter Australia.  In some circumstances, departure from Australia may impact on your ability to satisfy the criteria for the grant of a visa.  We cannot give you advice or information about this.  For more information, visit the Department's website.
