Hello, I used to be an international student, I claimed refugee and received a work permit, my question is how can I update the old SIN? When I try, in the plattform there is not an option for refugee claimants, only for other kinds of migratory status, I am not a temporary resident so, I am not sure, it is supposed that I should use my Aknowledgement of Claim, but I do not see that option either in that web page of Canadian government for SIN, so what am I doing wrong? Thanks.
