If you are planning on going to an English speaking country to learn English, then these are the main countries that speak English. They are all good options to go to and learn English and they have English language schools where you can have native English speakers as teachers. I recommend going to a smaller city if you really want to improve your English because in a big city it is common to meet people from your own country and then you never practice English. If you need to find a job, then Dublin is a great option because you can get a student visa that allows you to work and study.
