I received in the mail on March 14th our NOA2 with a Notice date of March 6, 2007 (saying our petition has been approved). I have been calling the National Visa Center to see if they have assigned us a case number, but still nothing as of today. Then tonight I received an email from the CSC saying they approved our petition and sent us our NOA2 in the mail on March 27th. We have already received our NOA2 in the mail! Are they sending us another one? Our on-line account has finally been updated today saying we were approved and the last touch was on March 28th.
I don't understand, especially why the dates do not match up. And we still do not have a case number from the NVC. I guess we just keep on waiting...
