Australia will abolish a temporary work visa popular with foreigners and replace it with a new program requiring better English-language and job skills, Prime Minister Malcolm Turnbull said on Tuesday. Turnbull, struggling with poor voter approval ratings, rejected suggestions the visa policy change was in response to far-right wing political parties, such as One Nation demanding more nationalistic policies. But in a Facebook announcement Turnbull said: "Our reforms will have a simple focus: Australian jobs and Australian values." Turnbull said the visa change would attract better skilled workers and see Australians employed over cheap foreign workers brought in under the old 457 visa program. "We are an immigration nation, but the fact remains- Australian workers must have priority for Australian jobs," he said. "We'll no longer allow 457 visas to be passports to jobs that could and should go to Australians." The 457 visa was introduced in the 1990s to expedite the entry of business professionals and highly skilled migrants but over time it was opened up to include a broad suite of workers. The program has become mired in controversy with allegations the visa was being misused by employers to import workers on the cheap, not to fill genuine skill shortage. "We are bringing the 457 visa class to an end. It's lost its credibility," Turnbull said at a press conference in Canberra. Anyone now in Australia on a 457 visa will not be affected by the new arrangements. Meanwhile, US President Donald Trump was to sign an executive order on Tuesday directing federal agencies to recommend changes to a temporary visa program used to bring foreign workers to the United States to fill high-skilled jobs. Two senior Trump administration officials who briefed reporters at the White House said Trump will also use the "buy American and hire American" order to seek changes in government procurement practices to increase the purchase of American products in federal contracts. The order is an attempt by Trump to carry out his "America First" campaign pledges to reform US immigration policies and encourage purchases of American products. As he nears the 100-day benchmark of his presidency, the order will call for "the strict enforcement of all laws governing entry into the United States of labor from abroad for the stated purpose of creating higher wages and higher employment rates for workers in the United States," one of the senior officials said. The order will call on those four federal departments to propose reforms to ensure H-1B visas are awarded to the most skilled or highest paid applicant. H-1B visas are intended for foreign nationals in "specialty" occupations that generally require higher education, which according to U.S. Citizenship and Immigration Services (USCIS) includes, but is not limited to, scientists, engineers or computer programmers. — Agencies
