The U.S. immigration service will extend the validity of certain work permits for some specific immigrant categories for one to two years, in order to alleviate the backlog of applications in immigration courts and offices.
The Office of Citizenship and Immigration Services indicates that the categories for those applying for this extension are:
Asylum seekers and refugees with deportation withholdings or in the process of deportation;
Self-petitioners who are victims of domestic violence
Immigrants protected by a temporary deferred action (other than DACA).
