Illegal immigrants skipping deportation hearings surged in the second term of President Obama's administration, pushing the 20-year average to 46,000 a year, according to a new analysis.

The figures indicate that 43 percent failed to appear at scheduled hearings in 2015, up from the 20-year average of 37 percent during which 918,098 were no-shows.

A Center for Immigration Studies found that over those 20 years, 338 illegals who failed to appear arrived from nations that sponsor terrorism.

The bulk of those who fail to appear are ordered deported, though the sheer numbers of no-shows has swamped federal immigration police, said the report.

In fact, since 2002 the list of illegals ordered removed has reached historic levels, but it is such a big job that "unexecuted removal orders" total 953,506. CIS said "an average of 25,107 unexecuted orders of removal were added each year through 2015."

The 20-year numbers analyzed by CIS are stunning. From its new report titled Courting Disaster:

Over the last 20 years, 37 percent of all aliens free pending trial failed to appear for their hearings. From the 2,498,375 foreign nationals outside detention during their court proceedings, 1,219,959 were ordered removed, 75 percent of them, 918,098, for failing to appear.

That 918,098 is larger than the population of San Francisco, and twice the population of Atlanta.

Chronic absconding from immigration courts continued unabated. Most telling of all, the number of illegal aliens present in the United States at the end of Barack Obama's second term — 11 million — is the same as it was in 2005 when George W. Bush began his second term. This is not how we define progress," wrote report author Mark H. Metcalf, a former judge on the immigration court in Miami, Fla.

"Stasis and failure are not new norms in American immigration, but merely old ones starting a new decade. Courting disaster is not an accident but, instead, a policy disconnected from rule of law and common sense that counts dysfunction as success and disorder as the price of progress, even at the loss of American jobs and the cost of American lives," he added in the report seen here.
