Hi Parveen,
you are asking the questions which we all ( all the applicants who lodged 189 visa, paid fee and been waiting for more than 7 months ) have. unfortunately, all we have are educated and logical guesses and no clear cut answers. if i have to take a logical guess on why the DHA is still inviting candidates for 189 visa …let me thing out loud… please be informed that the current cut off score for 189, lets say software engineer/analyst programmer/developer is 85 points. which is very high and out of reach for most of the applicants, also, the number of invites have been drastically reduced from 1500’s to 100 from couple of months, so this tells us that 189 will be a bit rare in the coming days and most of the applicants will take a detour and chose the 190 path. also, please note that processing times for 190 is 9 to 10 months where as , processing times for 189 are , well, 11 months to 22 months. only the exceptional people who can get 85-90 points will be invited and apply for 189 and will be processed in 11 to 22 months and the great thing about this is that they will know that their application will be processed in 11 to 22 months and unlike us ( we initially thought that our applications will be processed in 5-6 months) so, at least they will be in a better position in terms of planning.
The last grant as of now for 189 is on August 1st according to this forum…we can’t be sure whether the data could be accurate, may be there are folks out there who are receiving 189 grants while we are chatting here in this forum…we could never know…so we need to hang tight and wait for our turn. cheers mate!
