Urgent: Need Job Search Tips After Visa Sponsorship Rejection.

Hi all, I’ve been job hunting for 2 months with no luck, mainly using LinkedIn. I’m applying for public health job roles. I got one interview call, but they rejected me because I marked “Yes” for “Do you now or will require visa sponsorship in the future?” on the application. I’m on an F1 visa with OPT eligibility. Any tips on better job search platforms, clarifying visa status, or standing out? Thanks!
