I've also read that people sometimes have issues getting the stamp as well as people getting mixed responses from the help hotline.  There are no clear rules that I've seen.  I figured with in a month before the NOA expired and crossed my fingers.
 
When my husband got the stamp he said there was another person before him doing the same thing.  You can try asking if anyone else has tried using the field office you'll need to go to and if they had any issues.  I don't see any specific forum for field offices so maybe a new topic with the field office in the title.

Just wanted to report in that there were no issues getting the stamp at the Manchester Field Office (NH).  They did take away his green card, as expected, when they put the stamp in his passport.  At least he's all set for another year.  I am hoping that we start seeing Feb 2016 filers approved next month.

We went through US customs at Dublin airport earlier this month, and the person we spoke with told us they go by the date on the NOA letter. If we plan to travel out of the US again after the Feb expire date, we need the stamp.
