Protecting Children Through Eliminating Visa Loopholes Act This bill requires an alien who seeks to qualify for a nonimmigrant visa as the fiance or spouse of a U.S. citizen to be at least 18 years old, and the sponsoring U.S. citizen must also be at least 18 years old. The bill also establishes that the terms "spouse," "wife," and "husband" shall not apply to any individual less than 18 years old for the purposes of the immigration and nationality laws.
