Yes, of course. The sign language has become a popular form of communication in the city of Chicago as the numbers of hearing impaired people are increasing in the city; it has been a widely prevalent language in the city. There are a number of courses and tutors available in the city who guides the people of this language.

There are some schools and Universities too, which impart the education on sign language to the deaf students who have enrolled in their institutions, so as to make them learn new things and face the world inspite of their disability. The American Sign Language is widely practised in the city.
