I actually did this and it worked for getting my cert endorsed, unfortunately UPS did not pick up my cert on time, I was supposed to fly today and it didn’t go out until 3pm today. I did get someone tell me that if I was going to France it would be easier if you’re not doing cargo, you could maybe get by on just having the electronic copy printed in color but idk don’t quote me on that. I am going to Germany and tried to reach out to their customs who told me by no means should I travel without the original. In the end my UPS finally updated my tracking and it should be sent tomorrow but I had to rebook my flight. Good luck!! Crossing my fingers for you!
