Listen my experience in Labor dept... I am diploma engr and working as manager for Italian comp..my contract shows 15.6K basic salary ( every month company transfered more than 25k including OT)+ house and trans by the company.. .by mistake my comp provided me with technicians visa.. I have house contract , 2 yrs bank statement with 200k balance ..I have electric bill ..marrg cert attstd.. everything I have..still they rejected my family visa....they called me for interview..I went with all the original documents..they didn't asked anything ..just verbally asked about basic salary ..told me to check in website...again rejected... I really hate this type of system....IF they are not asking anything in the interview why they are calling us for interview...???? ..Good luck to you
