I was just online playing with InfoPass, and selected option 5 - "You have received an approval letter or Form I-797C from the Service Center or local office instructing you to come into the office for alien identification card processing / passport stamp."
After "Continue", it says "At this time, there are no information appointments available for the office in your area. Please try back again later."
Is this normal? Do you guys all have to keep coming back and try your luck?
