Hey everybody - I read on another thread that USCIS is now acknowledging the confusion regarding when exactly the extension letter expires, and as far as we know, they will allow us to make an infopass appointment to get the I-551 stamp 11months after the date on the letter. For example, my letter has the date July 17, 2016, so anytime after Aug 18, 2017, I can get the stamp. Loophole closed, I can visit my family this summer, whether or not I have my new greencard! Whee!
