American Sign Language (ASL) is a visual language. When signing, the brain treats linguistic information through the eyes. The shape, position, and movement of the hands as well as facial expressions and body movements play an important role in conveying information.
Sign language is not a universal language – every country has its sign language and regions have dialects, as do many languages spoken around the world. Like other spoken languages, ASL is a language with unique grammar and syntactic rules. You can also hire sign language interpreting agency via the web.

ASL is used primarily in the United States and many parts of Canada. ASL is accepted by many high schools, colleges, and universities according to modern and "foreign language" requirements for a degree in the United States.
The demand for skilled translators is in many places: K-12 education translation and higher education; in the community, for example at doctor visits, court appointments, and business meetings; and for the provision of Video Relay Services (VRS) and Video Remote Translation Services (VRI).
Deaf and hard-of-hearing people deserve an interpreter who knows what they are doing and does it well. A qualified translator is someone who can interpret both receptively and expressively accurately, effectively, and impartially using the special vocabulary required.
