Can't speak English, is it suitable for emigrating to Greece?

Greece mainly communicates in local Greek, but because of the development of tourism, most people can speak English more or less. I went to play for a few days before, and I feel that communication is ok, but if immigrants settle down, I think the language problem should be carefully considered. My sister who went to play with me before also discussed this issue with me, so I asked her if you would like to immigrate to Greece in the future. She said no, because of the language problem, even if you want to find a job, it may not be easy to find it. Actually, it's not just daily communication, including I went to the supermarket to buy a bag of potato chips. I can only tell the taste by pictures. I basically speak English, but people don't write English on the packaging. So, to sum up, learning Greek is more suitable for immigrants to settle down, and a little knowledge of English may be helpful, but if it is not a tourist area, I can't guarantee the English level of local people.

I hope answering the question for the first time can help you a little ~ but Greece is really a good place. People are very enthusiastic, the scenery is very good, and there is a deep cultural heritage. I had a good time in those days ~ ~ ~
