Yes, That was my only RFE. No year was printed on the boarding pass. I sent other proof that had dates but they sent RFE anyway.
My reply to RFE was again copy boarding pass front and back, the luggage claim sticker on the back had the complete date. In addition I sent copy of my flight confirmation, receipt of purchasing the airline ticket, and copy of all pages of my U.S. Passport even though it is only valid for 3 more years.
Six weeks later we received NOA-2
