The question of "why did everyone else who did it the way I did it get something different" only counts if *everyone* completed early and graduated early. Then it's worth noting that it's a visa officer level decision.
My question is i did 2 years post graduate study but i got only 1 year PGWP what i need to do get 3 years PGWP . I have completion letter from college stating i did 2 year program and letter of acceptance stating program length. so kindly suggest how i can amend the decison or i need to reapply
