My conditional green card will expire on sept 15 2011. I filed I-751: 2011-6-16 Biometry: 2011-7-16 I am still waiting for the renewed green card. Does anyone know how long it will take? Well, I got a receipt letter, which automatically extended my green card for one more year, so it is not urgent. But I am moving in the near future, so I do not want to check my mailbox every other day. It is boring.
