According to you, which country should I choose for my studies abroad?

The United Kingdom (UK) is a strong choice for your Master's, given your background in Dentistry, three years of work experience, and plans to take the IELTS. The UK offers a shorter program duration (typically 1 - 2 years) and a two-year post-study work (PSW) visa, allowing you to gain international experience quickly.

If budget is a key concern, Ireland is a good alternative with lower tuition fees and a similar two-year PSW visa. New Zealand offers the longest PSW visa (up to three years), which is beneficial if you want extended work experience abroad, but tuition fees are generally higher.
