Immigration-related site visits are a routine but important part of employment-based immigration compliance. Depending on the program, a government officer may seek to verify information in an immigration filing, confirm the worksite, review employment records, or ask limited questions about a sponsored employee’s job duties, wage, schedule, or reporting structure. U.S. Citizenship and Immigration Services (USCIS) has described H-1B site visits as both targeted and random, including unannounced visits, and the Department of Homeland Security (DHS) notes that STEM Optional Practical Training (OPT) employer site visits are intended to confirm information reported on the Form I-983 training plan. L-1 and R-1 employers may also be subject to site visits.
