回复:485 deadline: Postmarked or
In my I-797C for Notice of Action of I-485, There are two items concerning the time:
1) Received Date (this date is definitely 3 business days later than the day I mailed out);
2) Notify Date (the day they mail out I-797C). There is no information for postmarked date or mailing date.
I'm not sure others.
