My English is very good. Can I travel to different countries?

If English is good, most countries (British colonies, such as the United States) will be fine. I went to Korea the year before last. On the way, the director told us that the education level in Korea is still relatively high. If you are good at English, you can have a simple communication with them.

To sum up, the following three types of countries can communicate in English:

Once a British colony;

Most developed countries are countries with relatively high education level;

Nowadays, in order to develop tourism, a few developing countries require English-speaking tour guides in famous scenic spots.

Also, English is the most popular language at present, so if you know English, you can travel to most countries.
