The Washington Times reports on some possible corruption in US federal immigration services (H/T Bryan at Hot Air):

criminal investigations report says several U.S. Citizenship and Immigration Services employees are accused of aiding Islamic extremists with identification fraud and of exploiting the visa system for personal gain.

The confidential 2006 USCIS report said that despite the severity of the potential security breaches, most are not investigated "due to lack of resources" in the agency's internal affairs department.

According to the document, other potential security failures include reports that:

Employees are sharing detailed information on internal security measures with people outside the agency.

A Lebanese citizen bribed an immigration officer with airline tickets for visa benefits.

A USCIS officer in Harlington, Texas, sold immigration documents for $10,000 to as many as 20 people.

Last week, The Times disclosed a confidential DEA report substantiating the link between Islamic extremists and Mexican drug cartels. The 2005 DEA report states that Middle Eastern operatives, in U.S. sleeper cells, are working in conjunction with the cartels to fund terrorist organizations overseas. Several lawmakers promised congressional hearings based on the information disclosed in the DEA documents.

The DEA report also stated that Middle Eastern extremists living in the U.S. — who speak Spanish, Arabic and Hebrew fluently — are posing as Hispanic nationals.

USCIS Director Emilio Gonzalez in March told Congress that he could not establish how many terror suspects or persons of special interest have been granted immigration benefits.

Some are concerned about the national security implications of this potential corruption.
