RUMOR: The 14th Amendment guarantees citizenship to children born to parents illegally in the U.S. Critics argue that automatic birthright citizenship could be changed by revoking the statute. Others say it would require a constitutional amendment because they believe the 14th Amendment requires birthright citizenship.
Answer: Each child can only be claimed as a dependent by one parent (except when married couples file taxes jointly). Typically, in the case of divorced, separated, or never married parents, it is the custodial parent who is legally able to claim a child as a dependent for tax purposes.
When the non-custodial parent is claiming the child as a dependent/exemption/child tax credit; the custodial parent is still allowed to claim the same child for Earned Income Credit, Head of Household filing status, and day care credit.
