"U.S. Citizenship and Immigration Services (USCIS) announced today that
it extended an accommodation for H-2A workers in the sheepherding
industry to transition to the three-year limitation of stay
requirements. USCIS will require H-2A sheepherders who have reached
their maximum three-year period of stay to depart the United States by
Aug. 16, 2012. These sheepherders must then remain outside the country
for at least three months before petitioning for H-2A classification
again." - USCIS, Apr. 5, 2012.
