What the governing framework requires

An L-1B beneficiary may work at an unaffiliated client location, but INA §214(c)(2)(F) imposes additional restrictions when the beneficiary will be stationed primarily offsite. The petitioning organization must retain the required control and supervision, and the placement must be connected with the provision of a product or service for which the petitioner's specialized knowledge is necessary rather than an arrangement to provide labor for hire.

Offsite L-1B employment has its own statutory restrictions

The L-1 Visa Reform Act added special requirements for beneficiaries stationed primarily at unaffiliated worksites.

The issue is not merely where the employee sits but who controls the work and why the beneficiary is placed there.

The petitioning organization should principally control the beneficiary

The record should identify who assigns work, evaluates performance, approves leave, directs methods, manages deliverables, and retains personnel authority.

A conclusory statement that the petitioner controls the worker may be insufficient when the actual project documents suggest otherwise.

The placement should require specialized knowledge related to the petitioner's product or service

The beneficiary should not simply fill an ordinary client staffing need.

The petition should explain how specialized knowledge of the petitioner's own products, methods, services, systems, or processes is necessary at the client site.

The relationship should not resemble ordinary staff augmentation

Where the unaffiliated client controls day-to-day work and the beneficiary performs duties based principally on the client's systems or needs, the arrangement can raise serious statutory concerns.

Client and vendor documents should support the petitioner's explanation

Master service agreements, statements of work, project descriptions, client letters, reporting structures, and deliverables can be important.

Inconsistency among these documents can undermine the claimed control structure.

Document both employer control and the specialized nature of the placement

  • Statement of work
  • Client agreement
  • Project description
  • Petitioner supervisor evidence
  • Reporting procedures
  • Performance review structure
  • Petitioner product or service documentation
  • Client confirmation where useful

Frequently asked questions

Can an L-1B employee work at a client site?

Yes, potentially, but special statutory restrictions apply when the beneficiary is stationed primarily at an unaffiliated worksite.

Who must supervise an offsite L-1B employee?

The petitioning organization must retain the qualifying control and supervision required by the statute.

Is staff augmentation allowed?

An arrangement that is essentially labor for hire for an unaffiliated employer can violate the L-1B offsite restrictions.

Can the client assign some tasks?

The complete control arrangement matters. The petition should establish that the petitioner retains the required principal supervision and control.

Why are statements of work important?

They can show who controls the work, what service is being supplied, and why specialized knowledge is necessary.

Does specialized knowledge of the client's system qualify?

The offsite statute focuses on specialized knowledge related to the petitioning organization's product or service rather than ordinary labor supplied to the client.
