So far all of the approved PRTDs under H&C here were issued fot those within the ages of 18 to 19. There are a few people who are in their mid 20s who got approved but they usually have some other excuse other than education, finance, and lack of a job. Mostly family concerns, health of a relative, or unbreakable obligations. I'm 21 and I'm a bit worried about my case. I do have family and Canada and a single aunt with no children who is willing to take me in so I can care for her once she retires. And my dad suffered from PDD, dangerous hypertension, and insomnia and was in need of care from 2014 to 2015.
Honestly, I'm still not sure if that would cut it. People here haven't been very reasuring and keeps telling me to go through the US boarder, as if getting a US visa is any easier.
