You can be perfectly fluent until the end of days in the foreign language, but the kid will not "look like a domestic traveler" once s/he opens the mouth. Unless the youngster lives in the "foreign country" at a relatively young age, there will be little doubt that s/he isn't "domestic."
All that said, the younger the better for any language learning. Language learning in later years settles in a different part of the brain, and is generally never as effective as learning as a young kid.
