Is sign language international? Or are there different types of sign language?

Sign language is not international. Every country has their own sign language just like they do with spoken languages. American Sign Language (ASL) is the native sign language of those living in the United States. Just like accents and dialects, regional signs and variations do occur in ASL. There are also other forms of sign language used in the United States that follow more of an English grammar, such as: Signed Exact English (SEE), Pidgin Sign Language (PSE), Manually Coded English (MCE).
