Don't worry much! Most armors, and specially the best ones, have no trim lines or nothings. This is one thing that makes this hobby fun!
And... as said, no, it wont be a problem for your clearance, deployment or SWAT badge. And anyone elsewhere that says so, is just wrong.
Although most of us are against recasting for the most, the 501st has no an official stand or policy against or in favor of it.
No worries bro.
About it being a recast of an original ANH armor, unless it is an RS Propmasters armor, I can asure you, it was not. No one owns moulds from an ANH armor other than them. And no one in the hobby making armors own a full an ANH original armor.
Let us know if you need anything. And post pictures! We love pictures.
