The nation’s already backlogged immigration courts might soon be thrown into more havoc as roughly half of their 220 judges will be eligible for retirement next year.

The Executive Office for Immigration Review, which oversees the nation’s 59 immigration courts, says the court already has 32 vacancies, contributing to the current backlog of nearly 350,000 cases. Judges are overwhelmed, and immigrants with legitimate asylum claims can spend years in legal limbo.

Meanwhile, immigrants without legitimate legal claims remain in the country, while Americans foot the bill for them to be locked up longer.

The Executive Office says its average retirement rate is only 5 percent per year — which would mean 11 judges retiring in 2014. But Judge Dana Leigh Marks, president of the National Association of Immigration Judges, fears increasingly difficult conditions are likely to push many to retire at the earliest opportunity.

“We are the forgotten stepchild. When Congress wants to fund immigration enforcement, they forget about the court,” Marks said.

She said it takes months to vet judicial appointees and even longer for judges to get up to speed.

Congress has aggressively boosted funding for immigration enforcement and detention, with the Obama administration deporting some 360,000 people last year. Yet, the courts have seen few additional resources. That’s even as caseloads have jumped 15 percent since 2011, according to Executive Office for Immigration Review Director Juan Osuna, who testified before a congressional subcommittee.

As far back as 2008, a Georgetown Immigration Law Journal article surveying immigration judges found they exhibited more burnout “than prison wardens and physicians in busy hospitals.” The judges blamed the stress on the pressure to adjudicate so many cases — and decide the fate of so many lives — in such little time.

Unlike other federal judges, immigration judges fall under the U.S. Department of Justice and are employees of the executive branch, not the judicial branch. Their caseload varies. In Honolulu, two immigration judges each have about 100 cases, while six judges in Houston have about 6,000 cases each, according to the nonprofit federal data tracker, Transactional Records Access Clearinghouse at Syracuse University.

Immigration judges have no bailiff, no court reporter and aren’t guaranteed a court clerk. And while a federal judge might lean on three law clerks to help with 400 or so complaints, three immigration judges generally split one law clerk for an average of 1,500 cases.

Immigration judges also shoulder a much greater share of the legal research than other judges because 60 percent of those who come before their bench cannot afford an attorney.

Brookings Institute Fellow Russell Wheeler said the delays create additional expense for taxpayers because individuals can spend more time behind bars waiting for their cases to be resolved at a cost of about $160 per night.

Not everyone wants more judges, though. The lag time allows those without legitimate legal claims to remain in the country longer, and some immigrants hope if they can fight deportation long enough, Congress will eventually provide them some form of amnesty. Others marry a U.S. citizen while waiting for their cases to be heard.
