can only adults naturalize (citizenship in U.S.)?

Factual Questions
1

I was looking at some tables in the report below and wondered if only adults (over 17 years old) can naturalize. I.e., if we’re told 500,000 people were naturalized in year XXXX, were they all 18 or over?

Thanks.

Nope – immigrant children get naturalized all the time. A particularly common example is through international adoptions, though that’s by no means all of them.

Thanks.

friedo is correct - the progression for my children was [ul][li]for the first six months after they arrived, we were officially foster parents[]then we applied to officially adopt them[]once the adoption was final, we applied for citizenship for them[/ul][/li]
We still have the little flags they got when they became citizens.

There’s also derivative naturalization, which is conferred upon the children of alien parents when the parents become citizens.

Did they have to take an oath and a test and all that?
