Question 55: How long do Supreme Court justices serve?
Official answers (any one counts)
USCIS accepts any of these answers. If the question asks for more than one, give as many as it asks.
- (For) life
- Lifetime appointment
- (Until) retirement
Grandpa explains
For life, kiddo: they stay until they retire or die. Nobody fires them for how they vote.
Careful: these are NOT the answer
These are the common mix-ups. The app uses them as traps so you practice.
- Ten (10) years
- Six (6) years
- Until age 70
