According to the Government Accountability Office (GOA), there are at least 266 immigrants who have overstayed their visas, now making them illegal and posing a serious national security threat. Not surprisingly, the Department of Homeland Security (DHS) is unable to locate these potentially dangerous illegals.

In testimony on May 21 before the Subcommittee on Border and Maritime Security and Committee on Homeland Security in the United States House of Representatives, Rebecca Gambler, Director of Homeland Security and Justice for GOA, said that DHS had identified at least 1,901 illegals who have overstayed their visas. Fourteen percent remain missing as of March 2013.

The report said that 481 of the cases were dealt with by Immigration and Customs Enforcement’s (ICE) Enforcement and Removal Operations (ERO) division. According to the report this was due to the fact that these cases presented “potential public safety threats.” ERO is “responsible for identifying and apprehending aliens who are subject to removal from the country, detaining these individuals when necessary, and removing aliens subject to removal from the United States.”

While ERO was handling 25.3 percent of the cases, another 15.9 percent, or 302, of those illegal overstays were changing their status to continue living in the U.S. Still another 711 (37.4 percent) had already left the country.

DHS is having a hard time keeping up with real homeland security it seems. All of these findings are a result of a review of a backlog in the summer of 2011 of 1.6 million overstays!

According to the report, 863,000 cases were removed because either the individual had left the country or had obtained a legal status.

How did they determine this? According to the report:

“DHS uses ADIS to match departure records to arrival records and subsequently close records for individuals with matching arrival and departure records. Unmatched arrival records—those that do not have corresponding departure records—remain open and indicate that the individual is a potential overstay.”

As of April 2013, DHS continues to maintain more than 1 million unmatched arrival records in ADIS. GAO’s preliminary analysis identified nonimmigrants traveling to the United States on a tourist visa constitute 44 percent of unmatched arrival records, while tourists admitted under a visa waiver constitute 43 percent. The remaining records include various types of other nonimmigrants, such as those traveling on temporary worker visas.

Two United States Senators, Homeland Security and Governmental Affairs Committee Chairman Joe Lieberman (ID_CT) and Ranking Member Susan Collins (R-ME) cited the report by the GOA and “revealed 40-45 percent of the estimated total population of illegal aliens — 4 to 5 million people – stayed past their visa expiration dates. But DHS’ U.S. VISIT program – which is supposed to identify people who overstay their visas by comparing entry and exit information – cannot keep up with the number of potential overstays it identifies by matching entry and exit records.”
