For a variety of reasons, I oppose Donald Trump's efforts to end birthright citizenship for children of undocumented immigrants and those in the US on temporary visas. And I have argued he deserves to lose the Supreme Court case on this issue. But unlike many other opponents of Trump's policy and of his constitutional arguments, I am not convinced birthright citizenship is the ideal system. It is, at most, only a second-best option, in the sense that it's better than the currently likely alternative.
Under current political conditions, that likely alternative is subjecting hundreds of thousands of children to deportation, and many adults, as well. Even though Trump's executive order is limited to children born at least 30 days after it was issued, the logic of his legal arguments would deprive millions of adults and older children of their right to live in the United States, as well. If the Fourteenth Amendment denies birthright citizenship to children of undocumented immigrants and temporary visa-holders, that fact did not begin suddenly in 2025, but must have been true all along. Thus, the likely consequence of a legal victory for Trump would be grave harm to millions of children and descendants of immigrants, plus severe damage to the American economy and society from the resulting deportations and legal uncertainty. In addition, millions of other Americans would find it difficult to prove citizenship status if it can no longer be done on the basis of a birth certificate.
