Use of representative in processing working permit

[denyelay]

Hi I need your help. I am presently working here in Hongkong. I got
my employer in Canada through a job bank. We did not use
representative in processing of documents in
Canada. We communicated privately without any
representative but when I processed my working
permit here in Hongkong I need to use agency
because I can't go out during regular days and I need
to use a representative and I believe my agency who process my permit is licensed. As my agency
explained to me because I did not have
representative in Canada who would authorize
them. Is it true? I need your help. I don't have
peace of mind because I don't know if the officer
will accept my explanation. Any idea about this
matter?
