2008 test · Question 57 of 100
When must all men register for the Selective Service?
Official USCIS answers
- at age eighteen (18)
- between eighteen (18) and twenty-six (26)
Why this is the answer
The Selective Service System keeps a list of men who could be called for military service if needed. Federal law requires men to register when they turn 18, and they can register until age 26.
💡 Memory tip: Remember: 18 to 26 — the age range for Selective Service registration.
