English is not widely spoken in any Vietnamese city. Hue is no exception. You will have no difficulty finding someone who speaks English in any tourist facility (hotels, bars, restaurants, shops, etc), but it may not be easy to talk to someone you meet in the street. Young people study English in the school, but most of them are not fluent because they do not have many chances to practice it. Older people speak Russian and French as a second language depending on their age. The oldest ones learnt French during the last days of the French domination. The generation that studied during the first years of the communist regime, learnt Russian. Other foreign languages are hardly spoken.
