Hi, Does anyone here applied for a 457 subsequent entrant visa starting July 2017? I lodge my husband and kids subsequent visa 10th of july 2017. Until now the status is "recieved". The waiting game is killing me. The thing is I am now paying their health insurance monthly eventough they were still not here and doesnt have a visa yet. Should I contact the immi and send them an email to ask an update? Is there anyone here who lodge their visa after the changes on july 2017 and approved already?? Thanks a lot.
