But I have not receive approval notice or green card yet.
Actually I received two messages on the web:
1) Previous one:
On June 21, 2008, we mailed you a notice that we have approved this I485 APPLICATION TO REGISTER PERMANENT RESIDENCE OR TO ADJUST STATUS. Please follow any instructions on the notice. If you move before you receive the notice, call customer service.
2) Current one:
On July 8, 2008 we mailed the document to the address we have on file. You should receive the new document within 30 days. If you do not, or if you move before you get it, call customer service.
What do they mean sending me new document?
