Anyone who is born in South Carolina is automatically considered a U.S. citizen regardless of their parents' immigration status. In 1898, the U.S. Supreme Court affirmed the concept of 'birthright citizenship" in a case involving a Chinese-American who was refused re-entry to the U.S. after visiting China. The court decided that the United States' founders had written birthright citizenship into the 14th Amendment after adopting Anglo-American laws dating back to 1608.
Although legal experts have considered birthright citizenship to be settled law since 1898, some controversy has arisen about the concept. As part of his Republican presidential campaign, candidate Donald Trump has outlined an immigration plan called 'Defend the Laws and Constitution of the United States." Part of Trump's immigration plan calls for an end to birthright citizenship.
Commenting on Trump's immigration plan, the Dean of the University of San Francisco Law School said that an end to birthright citizenship in the U.S. is unlikely. He said that such a challenge to the Constitution would probably not be successful. If birthright citizenship were to end, the change would affect millions of people who were born in the United States.
Some people who were born in the United States end up spending the majority of their lives in another country. When these people wish to re-enter, they may want legal assistance proving their birthright citizenship status while applying for a U.S. passport. An immigration attorney may also be able to help with U.S. citizenship and possibly to petition for family members who would like to immigrate to the U.S.
