Many of DHS’ most fundamental operations won’t be impacted.
A number of DHS programs are funded by fees, rather than congressional appropriations, and would continue to operate even if funding lapses.
Those include the bureau’s cybersecurity operations and the Federal Protective Service, the law enforcement agency that oversees federal buildings. Border security efforts, the TSA and intelligence gathering efforts, among others, are all key DHS activities that would remain.
FEMA’s disaster relief operations and the national flood insurance program would continue to operate.
And most U.S. Citizenship and Immigration Services operations, including the visa program, immigrant naturalization and asylum claims, would continue — except for the E-Verify system employers use to verify workers’ visas, which would pause in case of a shutdown.
