We applied for immigration to canada earlier and got our PR status/card but have not met the 2 years in 5 years PR obligation. Our PR card expire on 2019. We currently live in the USA on a work visa and with all the new regulations being put in feel very stressful living here. We would like to reapply for immigration to Canada and checked that we have the necessary points to qualify under the Express Entry category. I know we will have to renounce our current PR status to reapply but have the following questions: 1. Will they reject our application if we don't give a strong reason to why we did not immigrate in the past. 2. To save time, while our reapplication is on process, can we renounce our current PR status and once renounced update them?
