MyOmniCareer
A job search portal built around visa sponsorship: every listing carries a score for how likely sponsorship is (confirmed, likely, possible, or not sponsored), and you can filter by country, field and work mode. Upload a resume and it also scores your match against jobs and helps with applications. Free during its early access period, with no card required.
Why I recommend it: Useful if you are looking for work in a country you need sponsorship for, which almost no mainstream job board tells you anything about. Two honest cautions: it says free during early access, so free today does not mean free next month, and a sponsorship score is the site's guess from a job posting, not a promise from the employer, so confirm with the company before you build plans on it. Uploading your resume means handing it to their AI providers.
