O Gorman Trevor and some don't, so we are trying to determine if it's mandatory or not since some people may need to scramble and beg for physical copies if so
To clarify, you went to your embassy and they handed you a physical paper letter with an original seal, not a printed copy ? You may be the first person to receive an extension, so we are trying to work out the details since most embassies will only give a email pdf which we all print. A letter with a seal would be a different process.
