hello everyone! I just wanted to ask. My work permit (Live-in Caregiver program) and trv will expire on April 13, 2018. I came here in canada June 2016. The validity of issued work permit and trv was based on the expiry of my passport. I already got a new passport and now i will file for work permit extension. My question is How long (minimum/maximum months/years) must i put for length of request extension?
