Not sure about the service in AIVES Bangalore, but a friend of ours had their application done by their office in Dubai and they got a very good service. I think they got their PR in 6 or 7 months. I also went to their office and met the MARA registered agent Rasheed Backer. They seemed very professional and know what they are doing.
Hi,
I have got a friend who wants to apply as a teach as well, but I believe that now you need to have a bachelor's in education that is equivalent to an Australian degree. Not sure if they have changed the requirement though
