Career Advice: Job Overseas

I’m exploring opportunities to move abroad for work and would love some guidance. I have 4 years of experience in AI/ML (model building, deployment, and data science work). For someone with my background, what’s the most effective strategy to land a job overseas?

Would it make more sense to apply directly to companies, focus on internal transfers, or target countries with easier tech-visa pathways? Any firsthand experiences or practical tips would help.
