As of October 1, 2017, USCIS will be implementing a new step for Adjustment of Status applicants whose cases are employment based and Refugee/Asylum relative petitions for beneficiaries who are in the US and are applying to join the principal Refugee/ Asylum applicant. Applicants who are in these two criteria will now be scheduled for interviews as a part of the adjudication process for their case.
The interview process is a way to further vet applicants on the information provided by the applicants in their application and to discern more information from applicants. In other words, a more extensive screening process.
Previously these two categories were not subject to an interview but with the Executive Order 13780 – “Protecting the Nation from Foreign Terrorist Entry into the United States” – this could be the first of many changes that USCIS decides to implement. The requirement for an interview may also spread to other visa types and categories as well.
