What is “on-site” vs “off-site” employment in the H-1B?

In the context of the H-1B, the terms “on-site” and “off-site” describe where the professional actually performs the work. The distinction matters because the visa is tied to a worksite declared in the petition, and location changes can have implications.

In summary:

• On-site: work takes place at the employer’s own facilities, at a fixed and well-defined location, typically with direct supervision and a more structured routine.
• Off-site: work is performed outside the employer’s headquarters, such as at the end client’s site, in the field, or in a remote-work arrangement, with the location potentially varying.

Off-site flexibility is common, especially in outsourcing and client-placement models, but it does not loosen the obligations: the employer remains responsible for maintaining the conditions declared for the visa, and significant worksite changes may require formal amendments to the petition. Ignoring this can put the visa status at risk.

Since each arrangement has its own particularities, it is worth checking the updated rules at the official source (USCIS) and aligning with the employer and an immigration professional before changing the work format or location.
