Some of the countries’ permanent residency can be based on work skills and business etc. Following are the countries where you have more chances of getting a permanent visa than any other country

Countries you can immigrant easily:

CANADA: Canada even though cold country students are tempted with its visa rules and PR (permanent residency) system. Being multicultural and close to the USA, and one of the best countries to live in, students congregate to Canada, regardless of their choice of course and university. Finish one year course and you get the one-year visa extension. Finish two-year course you get the three-year visa extension for the job. If you get a job, you apply for PR after 6 months and sometimes immediately and within two years you become Canadian Citizen.
Australia: Regardless of racism and the heavy tuition fee, students care about the 2-3 year Visa extension after their education. With a high standard of living and better job prospects and easy PR rules, Australia is one of the most famous studies abroad destination among students in Bangladesh. A student can get PR in Australia within two years as well but have to spend 50000-70000 USD for education.
New Zealand: New Zealand’s population is aging day by day and the government requires international students to contribute their country’s economy. With this motto, the PR rules in the country have been relaxed. You can study in New Zealand with a minimal tuition fee compared to Australia and you get the visa extension for 2 years and settle there after your PR is processed within three years.
Ireland: You get one-year visa extension after finishing your one year program in Ireland. For PR/Green Card application it takes 36 months to process. Major sectors like information technology, engineering and medical are intact.
USA: Getting the green card in the USA is like dream come true. It takes minimum 10 years to get your visa processed. After completing your education you get a two-year visa extension. But the US is still a country well known for its university reputation, lifestyle, and technology, everyone dreams it.
European Countries: In European countries, visa regulations are quite strict and local language of the country has to be known to apply for Green Card. Also, processing time is very high. However certain employment card allows you to work as much as you want but won't be able to enjoy the benefits of a citizen. For example, blue card in Germany.
