halcyonstorm asked: Hello :) I was wondering, how much trouble would someone have either visiting long term or moving to live in Iceland permanently if they spoke only English and no Icelandic?
Pretty much everybody in Iceland speaks good English, so getting by on English alone is generally easy. Of course if you are thinking within the workplace, then that varies. Depending on your line of work, there are plenty of companies that have non-Icelandic speaking employees. Tourism, software as well as plenty of labor jobs.
