Acquisition of citizenship
There are various ways a person can acquire United States citizenship, either at birth or later on in life.
[edit] Birth within the United States
Main article: Birthright citizenship in the United States of America
Main article: Jus soli
The Supreme Court has never explicitly ruled on whether children born in the United States to illegal immigrant parents are entitled to birthright citizenship via the 14th Amendment,[5] although it has generally been assumed that they are.[6] A birth certificate issued by a U.S. state or territorial government is evidence of citizenship, and is usually accepted as proof of citizenship.
In the case of United States v. Wong Kim Ark, 169 U.S. 649 (1898), the Supreme Court ruled that a person becomes a citizen of the United States at the time of birth, by virtue of the first clause of the 14th amendment of the Constitution, if that person is:
* Born in the United States
* Has parents that are subjects of a foreign power, but not in any diplomatic or official capacity of that foreign power
* Has parents that have permanent domicile and residence in the United States
* Has parents that are in the United States for business
Dakle (provereno u svakodnevnoj praksi) - ako roditelji legalno borave u USA na bilo kojoj vizi osim turisticke (skolska, studenstka, radna, exchange
scholar, inter-company transfer....) njihovo dete rodjeno na teritoriji USA rodjenjem automatski postaje US citizen. Ovo sam apsolutno
siguran da je tacno, jer u blizoj familiji imam takav slucaj.
Kako navodi wikipedija, detetu rodjenom od roditelja bez validnog imigrantskog statusa se de facto (iako ne de iure, tj. po zakonu) priznaje
drzavljanstvo (mada, kao da se secam da sam na radiju u kolima slusao neki slucaj gde to bas i nije islo glatko iz nekog razloga).
