Hi Faraz.. I order to apply, you should have a minimum of one year of full time work experience in any of those 29 categories. That list of 29 in demand jobs were for MI3 in fact (2011-2012 batch) which was closed 2012. However, MI4 is yet to open, As per CIC's recent update, new categories will be open on May first week, 2013. Prepare your documents by the time so that if your category is available, you can submit your application at the earliest. Because these categories get filled within a few days as they keep a minimum cap on the intake of applications. So prepare your documents, IELTS, reference letters from employers...etc
