If a company outlines in the job posting that they will not provide sponsorship, then you should not apply. To see whether a company will provide sponsorship for a job, view the job posting and check the details box to the right of the job description. You will see “Will Sponsor Visa: Yes/No.”
We recommend contacting the recruiter or employer directly with any questions about sponsorship. They will also let you know opportunities on our site they have listed that will allow you to apply without a Visa or sponsorship.
