The problem

International students lose hours
to jobs they were never eligible for.

Job boards let employers self-report sponsorship fields. Those fields can be incomplete, outdated, or contradicted by the actual job description.

Unreliable checkboxes

Employer-selected fields are often self-reported, incomplete, or never updated after the role changes.

Hidden contradictions

"Sponsorship available" in the filter, but "no visa sponsorship" buried in paragraph 8 of the description.

30–60 minutes wasted

Students spend up to an hour per application — only to discover restrictive language after submitting.

The solution

One click. Clear decision.

Handshake shows what employers selected. SponsorLens reads what the posting actually says.
