During the heyday of European immigration to the U.S. in the decades before 1921, there were a lot of children born to immigrants who grew up as Americans. Many of them gave their lives for the United States in WWI or WWII, or served honorably before producing hordes of monolingual third-generation Americans. Is the citizenship status of people born in the U.S. to legal immigrants to be questioned?

Not at all. It's very simple. According to the Constitution they are not citizens. When their parents are naturalized so are their minor children. If the children reach the age of majority before that time and qualify for naturalization by fighting for America or other appropriate means, I see no reason why Congress would not pass laws defining and securing such means. That is how it was intended and should be.

Er, no. The question raised was about legal immigrants, who clearly are "subject to the jurisdiction" of the United States (as opposed to illegal aliens, whose very presence here is a testament to their evasion of that jurisdiction).
