My wife and kids PR card is set to expire in March 2019. They never stayed in Canada so far. We are planning on moving to Canada in June 2018. When can i apply for their PR card renewal. Can i do it in Aug/Sept 2018?
No, you should not do it in August 2018. You need a minimum of two years residence in Canada per every five year period to maintain PR status in Canada. If they return to Canada in March 2019 and apply to renew their PR Cards prior to March 2021, they will be investigated and likely have their status revoked. Even if they apply after March 2021, they may be investigated. We recommend at least 3 years of continuous residence per every five year period.
Well, you can't travel outside without a valid PR Card unless you apply for a PR Travel Document abroad (which takes 3 weeks). But applications for PRTDs abroad can lead to your status being revoked if you don't meet the residence requirement. So, yes, we'd recommend not traveling for three years, though officially it's two years.
