During the outbreak, many people are working remotely from home. Mercurynews California reports that USCIS has recently begun sending home visits to H-1B employees to raid their homes and check for violations.
San Francisco BAL attorney Kelli Duehning says that during the outbreak, USCIS emailed her client's H-1B employees to set up a time to meet with them in their offices or at their homes. She knew of two H-1B employees who lived in Mountain View, California and Redwood City, California (near the headquarters of Google and other large companies) who were "visited" by USCIS at their homes without any prior notice.
Duehning said that this is not a very friendly approach by the USCIS, and that it can be intimidating for people who are not used to being visited by government officials, to have a knock on their door and start taking questions....
USCIS declined to say when it would begin making home visits, why it would visit, or details about how many home visits were made. USCIS spokesman Matthew Bourke said the agency has the authority to conduct on-site inspections of H-1B employees' workplaces to verify that visa holders are complying with the law and are not committing fraud or non-compliance.
In the past, USCIS has only gone to companies (workplaces) for verification. According to attorneys at the Washington, D.C. immigration law giant Fragomen, USCIS officers made virtual home visits to H-1B workers by phone or email in most cases during the outbreak, and there were not a large number of unannounced site visits.
The home visits that have occurred in California are a new sign that USCIS is moving with the times. source
