I also got a call from this number yesterday.

Also got a call from here claiming to be immigration and knew my name, it was very strange - called on a Saturday and requested we come back in for a follow up appointment. When we called USCIS back on Monday, they said it was probably a scam and that they would communicate by mail, and their employees wouldn't be calling on a Saturday anyway - also they had no record of the call. Beware other people getting this call.

Jessica from the Retirement Group telling me I need to attend an AT&T employees meeting.  Obviously a canned message, and received several of these in the past, always with a different voice but with the same message.  Very annoying.

Got the 559-000-0000 and no message. I believe it is from Telemarketers and anyone can change their phone numbers (aka Spoof Card).
