Student visas in crossfire of 457s THE TAFE sector has slammed the Rudd government's failure to extend streamlined student visa processing beyond universities, accusing it of conflating the issue with its crackdown on 457 temporary work visas. "The debate over 457 visas, and the inability of the government to clearly articulate the difference between somebody coming here to take up temporary work and someone coming here to study, led to complete inaction on extending streamlining," TAFE Directors Australia head of international development Peter Holden said.
