apply TRV in US(outside of Canada) with a valid post-graduate workpermit

[bottlezz]

Hi,

I am currently in US, and my visa has expired. I want to renew it before i get back to Canada so that i can go other country after finishing my visit of US.

However, every time I try the self evaluation tool, it will say i need to apply a post-graduate work permit first, but in fact i already have it.

Can anyone advice me how should I apply a TRV with a PGWP when i am outside of Canada?

thanks,
