As a result several government agencies, providing immigration-related services, are impacted:
Status: All USCIS offices worldwide are open and individuals should report to interviews and appointments as scheduled. Since most of USCIS’ budget is derived from fees paid by applicants and petitioners filing nonimmigrant and immigrant visa petitions, it is the least impacted government agency.
• E-Verify is currently unavailable due to the government shutdown.
Status: All DOL services are shutdown. DOL (OFLC) will neither accept nor process any applications or related materials (such as audit responses), it receives, including Labor Condition Applications, Applications for Prevailing Wage Determination, Applications for Temporary Employment Certification, or Applications for Permanent Employment Certification. OFLC’s web site, including the iCERT Visa Portal System, is static and unable to process any requests or allow authorized users to access their online accounts.
Status: Normal operations for the time being. U.S. embassies and consulates around the world will continue as many normal operations as possible; operating status and available funding will need to be monitored continuously and closely. Check the U.S. embassy/consulate website for more information.
