The Trump administration has empowered officials to outright outright reject visa applications under certain circumstances. This step can be taken if the required initial evidence was not submitted or it failed to establish eligibility for the visa sought. The revised policy will apply to all applications and requests received by the authorities from September 11 onwards.
In other words, the visa applicants, that include companies sponsoring H-1B employees, are less likely to get a second chance to submit more documentary evidence or provide explanations that would substantiate eligibility for the visa. In some cases, outright denial of the application, say for the extension of an H-1B visa, could even place the employee at the risk of deportation.
The governments failure to provide internal training can result in numerous denials, which are nothing less than clear abuse of discretion or application of a standard that is clearly erroneous. Based on these grounds, the visa applicant can file an appeal with the appeals office.
