Best Country for Master's as a Female Student with PR Pathway?

(Writing behalf of someone)

I have a BS in Biotechnology (CGPA: 3.55) from Virtual University and a budget of 3.5 million PKR for my . I'm looking for a country with good job opportunities, and an easy pathway to permanent residency after graduation. My preferred fields are biotechnology, life sciences, or related areas. Any recommendations on the best countries considering tuition fees, living costs, scholarships, and post-study work visas? How is Canada, UK or EU?
