I was wondering what it meant when they emailed me saying that they sent" a document that was made after approval or registration of case." they said that for the 485 and the 130 through email. i know that they send an actual card for the 485 but what the heck do they send with an approval of i-130? they also did not let me change the address for the 130 when i called the uscis..they told me i had to contact some national visa center or something.
