Congrats.
You would be fine... I took the oath today and there were multiple people with some kind of ticket, as long as you have a paper to show, you should be fine.
So finally took oath, before the oath, I had to give my green card away.... it was emotional... I waited for that green card for 7 years, spent several hundred hours in this forum reading about other people getting their green cards and having issues etc. for that green card. And today someone took it and after the ceremony they gave a paper with Naturalization certificate.
It was quite a journey, but in the end it's all worth it!
