For highly-skilled foreign workers applying for a new work visa or an extension, the stakes involved just got a whole lot higher.

The US Citizenship and Immigration Services recently updated its guidance, taking a much stricter approach to approving applications that are largely filed by those seeking work in the tech industry.

Under the new policy, which goes into effect Sept. 11, agents will be able to deny applications deemed incomplete or containing errors, without first asking applicants to address the flaw or warning them of an intent to refuse their submission. Recently the agency also widened the range of cases for which it could begin the process of removing foreign nationals to include those whose immigration benefits, such as work status, have been denied.
