The United States allows a quarter of a million Muslim immigrants to legally enter the country each year, according to federal data reviewed by Breitbart.

In 2013 alone, over 280,000 Muslim migrants were allowed into the country. Of those, 117,423 were given permanent legal status.

The U.S. also admitted an additional 122,921 foreign students and workers from Muslim countries in 2013.

The report comes as President Obama announced last week that the U.S. will take in at least 10,000 Syrian refugees over the next year as they flee their war-torn country, reported The New York Times. The top two House Democrats on the committee dealing with immigration want the U.S. to accept 100,000 Syrian refugees and 100,000 refugees from other countries next year, according to The Washington Times. Some worry that Islamic terrorists may be able to slip into the country disguised as refugees.

Between 2001 and 2013, the U.S. permanently resettled 1.5 million Muslim immigrants, Breitbart notes.

"Unlike illegal immigrants, legal immigrants granted lifetime resettlement privileges will be given automatic work permits, welfare access, and the ability to become voting citizens," said Breitbart's Julia Hahn.

The numbers are expected to continue to rise, and Middle Eastern immigrants now represent the largest group admitted through the visa process.

"Arabic is now the most common language spoken by refugees, and 91.4 percent of recent refugees from the Middle East are on food stamps," Hahn said.

One concern with Middle Eastern immigrants is how easily they can assimilate into Western culture, especially when it comes to practices such as female genital mutilation. "The importation of immigrants from predominately Muslim countries has not put half a million girls in the United States at risk of enduring" this practice, more than there are in Uganda and Cameroon, according to Hahn.

"Moreover, the importation of Muslim immigrants through the nation's refugee program has led to the development of pockets of radicalized communities throughout the United States," Hahn said, citing a review of recent terror activity provided by the Senate Immigration Subcommittee.
