Supreme Court to Hear Interesting Sex Discrimination and Immigration Law Case

This looks very very interesting and points out something I had no idea about

Now, the Supreme Court is entering a curious corner of U.S. immigration law that applies only to children born outside the U.S. to one parent who is an American and one who is not. The law makes it easier for children whose mother is a citizen to become citizens themselves. Even after reform legislation in 1986, children of American fathers face higher hurdles claiming citizenship for themselves.

Well that does not seem fair. See Court to weigh citizenship rule that varies by sex

Now they note the 1986 change to the law
When he sought U.S. citizenship in 2006 - to stave off criminal charges of being in the country illegally - U.S. immigration authorities turned him down. For people born before 1986, their U.S. citizen fathers had to have lived in the U.S. for 10 years, at least five of them after the age of 14. Flores-Villar's father could not meet the second part of that requirement because he was only 16 when his son was born.
American mothers need only have lived in the U.S. continuously for a year before the birth of a child.
Changes to immigration law made in 1986 reduced the total residency time for fathers to five years, only two of which had to be after the age of 14.

Now this presents a real problem does it not? There are a ton of Americans living abroad with their teenager in tow. What happens if you have been living and working abroad a number of years and your precious teenage son gets some foreign girl with child. If you want your grandchild to have American citizenship do you have to beg and plead the girls parents to let you take her to the USA to give birth?

I was always under the impression that if one of your parents was American you were in but just had to fill out some papers at birth.

I can imagine certain partsof the world where getting your grandchild Americna Citizenship would be HIGH PRIORITY
