Hi all just want to add my timeline for AIPP we ordered caips notes (haven't received yet) but our file seems to moving since we ordered them.
My wife is lead applicant there is six of us in total. We are from the UK. My wife's noc code is 4214. My noc code is 7321. My wife and I done upfront medicals but we did not get our children's medicals as we was not sure that they needed them at the time and my wife needed hers for her job. We have been requested to get medicals again, we think this is due to the medicals only lasting 12 months and its been almost 11 months since we did them.
First application for PR refused

on 3 August 2018, six weeks after they received it due to Education as they didn't understand her UK qualifications and the ICAS report didn't help either. We resolved this by sending a letter and further certification from other provinces with our second application. Its been a long and still on going process hope we all get somewhere soon.
WP applied for 24 May 2018 still nothing on that, when we contact them all they say is its still in process. (after 9 months we have given up on that)
