Tasse,
I have often wondered myself about this. It's about the JIT date, I presume. Here's the best explanation I found in this group after a lot of investigation:
You have a ND on your filing receipt. That's the first important date.
There is a JIT date for a certain kind of case, that's second important date.
There's the JIT issuance date, that's the third date.
The sentence says - you can fax an inquiry but only after the following two statements are truw:
1. JIT date is later than ND
2. Today's date is later than JIT issuance date by at least 30 days.
Example: Your ND for AP is 5/13. JIT date for AP is 5/12. JIT issued on 9/18. You can fax an inquiry if
1. JIT date is later than ND (it is, by one day)
2. Today's date is later than JIT issuance date by at least 30 days that means 9/18 + 30 which makes it possible for you to send a fax inquiry on 10/19 or later (if your AP is not approved by that time, of course)
