Is there any way to get more information about my file other than contact cic call center even if they charge for it?
You can request your file under ATIP for free but here are the caveats -
1. It will be generated the day of (or the day after) your request but you will probably receive the report after 30 days.
2. The information will probably be sparse. Security stuff will be redacted and other details bare. It could even be misleading if you see dates that are just placeholders (usually 1 year out from your AOR)
It can be useful in knowing which office your file is headed and has it already been sent to the office.
(I haven't ordered the report but that is the summary of what I have seen in these forums from people who have done it)
