I just spoke with the USCIS media representative (posed as reporter for local paper here in Hawaii since many of us have to fly over). If there is a government shutdown offices will remain open for interviews, biometrics, etc., because it is fee based. However, other services that involve other government agencies such as background checks, e-verify for employers will not be available.
Very happy about the fact that office will be open as Natz interview/test appointment on Thursday, April 14.
