What are the post-study work permit durations and job opportunities in countries like UK, Ireland, Singapore, and Dubai?

For post-study work: In the UK, you can work for up to 2 years after your degree. Ireland offers a similar 2-year stay-back period. Singapore requires a job offer to qualify for an Employment Pass, typically valid 1-3 years. Dubai provides a 6-month Jobseeker Visa and, once employed, a Green Visa for 5 years. Each country has strong job markets, but securing employment and meeting visa requirements is key.
