The letter you are actually waiting for is the acknowledgement letter
and the passport request form.
This is not sent by Air21 but rather though the local post,
really check on the local post office. Because of the previous holidays,
the letter might have been piled under other letters.
And I suggest you better do the email inquiry because
there were instances that CIC will not answer inquiries
by applicants when they still do not have a client ID number
(which you can get from the acknowledgement letter).
We call the contact numbers and they told us that they are using Air21.
I will have my wife send the email first and I will do a follow up. My ECAS
is showing Decision Made and its approved. This one is causing us delays
BTW ano ba ung included and need files sa letter na nisend nila? They told my wife that they only need the AOM and Appendix A
