The suspension affects work visas that many technology and landscaping companies in the United States now use. The move also affects visas for exchange students and heads of multinational companies. It also affects visas for nonagricultural seasonal workers. But there are exceptions for workers in food processing, health care, childcare, and agriculture.
这次暂停会影响到美国许多科技和园林绿化公司目前正在使用的工作签证。此举还将会影响到交换生和跨国企业负责人的签证。它还会影响非农业季节性劳工的签证。但是食品加工、医疗保健、育儿和农业领域的劳工例外。

The Trump administration said the decision to suspend some immigration visas was necessary to protect U.S. workers. More than 45 million workers have reported losing their jobs since the middle of March during the coronavirus pandemic. They have asked the government for assistance until they return to work. Many have since returned to their jobs as businesses reopen.
川普政府表示，暂停某些移民签证的决定对于保护美国工人来说是必要的。自3月中旬发生冠状病毒大流行以来，已经有4500万工人报告失业。他们请求政府提供援助直到他们恢复就业。此后，随着企业重新营业，许多人重返了工作岗位。

Business groups, however, strongly oppose the administration's decision. Technology companies and the U.S. Chamber of Commerce said banning foreign workers would hurt the country's economic recovery.
然而，商业机构强烈反对政府的这一决定。科技公司和美国商会表示，禁止外国劳工将会损害该国的经济复苏。

The effects of the ban may not be immediately felt. U.S. officials have approved few work visas because of travel restrictions during the pandemic.
禁令效果可能不会立即显现。由于大流行期间的旅行限制，美国官员很少批准工作签证。
