Thousands of requests by men to bring in child and adolescent brides to live in the United States were approved over the past decade, according to government data obtained by The Associated Press. In one case, a 49-year-old man applied for admission for a 15-year-old girl.

The approvals are legal: The Immigration and Nationality Act does not set minimum age requirements. And in weighing petitions for spouses or fiancées, U.S. Citizenship and Immigration Services goes by whether the marriage is legal in the home country and then whether the marriage would be legal in the state where the petitioner lives.

But the data raises questions about whether the immigration system may be enabling forced marriage and about how U.S. laws may be compounding the problem despite efforts to limit child and forced marriage. Marriage between adults and minors is not uncommon in the United States, and most states allow children to marry with some restrictions.

There were more than 5,000 cases of adults petitioning on behalf of minors and nearly 3,000 examples of minors seeking to bring in older spouses or fiancés, according to the data requested by the Senate Homeland Security Committee in 2017 and compiled into a report.

Between 2007 to 2017, there were 5,556 approvals for those seeking to bring minor spouses or fiancées, and 2,926 approvals by minors seeking to bring in older spouses, according to the data. Additionally, there were 204 for minors by minors. Petitions can be filed by U.S. citizens or permanent residents.

"It indicates a problem. It indicates a loophole that we need to close," Republican Sen. Ron Johnson of Wisconsin, the chairman of the Senate Homeland Security Committee, told the AP. In nearly all the cases, the girls were the younger person in the relationship. In 149 instances, the adult was older than 40, and in 28 cases the adult was over 50, the committee found. Among the examples: In 2011, immigration officials approved a 14-year-old's petition for a 48-year-old spouse in Jamaica. A petition from a 71-year-old man was approved in 2013 for his 17-year-old wife in Guatemala.

There are no nationwide statistics on child marriage, but data from a few states suggests it is far from rare. State laws generally set 18 as the minimum age for marriage, yet every state allows exceptions. Most states let 16- and 17-year-olds marry if they have parental consent, and several states — including New York, Virginia and Maryland — allow children under 16 to marry with court permission.
