I only found out a while ago that once your 18 years old in the US, you have to register for military service. I’m not 18 yet, not even a US citizen, but when are they supposed to find out about this? It was just by accident that I found out.
So, are you just supposed to know, or do they maybe send out a letter? How many US citizens are over 18 and walking around, not registered for military service? What if you were found out to not be registered?
