I decided to see if I could get an update on the kids' case status from the USCIS website and I was pleasantly surprised by how easy it was to use and how much information is available. If you've received your case-receipt email or I-797 form, it will have a receipt number on it (Sky and Fire's started with NBC). All you have to do is go to USCIS.gov and click on "Check Your Case Status".
Enter the receipt number in the box and it will bring up your case status (one of ours is pictured below).
You can also check on processing times for cases like yours. Click on the drop-down boxes (as shown above) to select the type of case you're filing and where you requested your hearing and it will give you the average processing time for similar cases. It was great to find out that we're only looking at a 5-6 month wait, since that's the next time we'll probably be heading off-island.
