Canadian immigrants have been approved, why not post them?

Because the trial time of labeling in Canada is unstable at present, we can try to urge the labeling. Another possibility is that there are some problems in the labeling application you submitted, which was judged as post-processing by the visa officer, and then rejected by the post-labeling person, resulting in being shelved.

If repeated reminders have no effect, or they are not labeled, then find a professional to check and let them analyze the submitted materials to see if there are any problems.

If professionals analyze the submitted materials and find that there are possible factors that refuse to mark the submitted materials, they can cancel the marking first and then submit the marking application, which can avoid long waiting and delay time.
