Interview scheduled!
The infopass was very weird, this is how it went:
-15 minutes before going in I call KCC and they tell me they sent my case to the local USCIS on April 5th.
-I step in and ask if they received my case. The guy said he received it 10 seconds ago and thus my interview is pending (!).
-I ask him what is a time frame when I could expect the interview to be scheduled in. He looks again at his computer, and he says "wait a sec, you are actually already scheduled for an interview." He goes in the back, probably to speak with somebody, and then gives me the date. He told me the interview notice should arrive very soon.
For how this whole thing happened I thought somebody was playing a joke on me. I just feel so lucky.
