"A few years ago, a school district in Texas found itself with a booming immigrant population and few teachers who spoke Spanish. So they started an ambitious recruitment program that brought in 260 teachers – from Colombia, Mexico and Venezuela – to meet their growing demand.
Now, about six years later, 23 of those teachers are facing deportation after the Garland Independent School District apparently bungled their temporary work visas, or H-1B. Federal authorities are investigating the school district over the blunder and an administrator, teacher and associate superintendent have been placed on leave.
The problem centers on work done by a law firm, which has since been fired. The firm allegedly asked the teachers to pay for the sponsorship of their H-1B, an apparent violation of the visa requirement. Federal law mandates that the sponsoring organization – the district, in this case, not the teachers – cover the $20,000 in costs for each applicant." - Fox News Latino, Mar. 27, 2014.
