"Passport Office"

[Goton564]

Shutters are terrible. give the office a button in the back that remotely drops and raises the door bolts on those airlocks.

Yep, that's a better idea. Just have to remember not to bolt the doors wide open!

Also, maybe make it like the airbridges (double doors) so only one guy can go at a time?
idk how annoying that would be though!
