my work petmit is approved

it says it takes 30 days to get it in mail. does it really take that long?

No, maybe, depending on where you live. its USPS.

i got approved yesterday too, i sent my application with less then 80 days from expiration and so happy and relief that i dont have to worry about this anymore.

3-9 days the most. They say 30 days just to allow themselves time to screw around should something happen.
