American Sign Language was introduced to the Philippines by Andrew Foster, a renowned deaf educator and missionary from the United States. Foster established a school for the deaf in the Philippines in the 1960s, where he taught American Sign Language and helped promote deaf education in the country.

The Philippines have their own sign language called Fillipino Sign Language, but a good portion of FSL is based on American Sign. The School for the Deaf and Blind was established in the Philippines back in 1907. This school was founded by an American teacher, Ms. Delia Delight Rice. This school was run by American principles until the 1940s.

American Sign Language (ASL) and Filipino Sign Language (FSL) are distinct languages with different grammar, syntax, and vocabulary. ASL is based on French Sign Language, while FSL has influences from Spanish Sign Language and indigenous Filipino signs. Additionally, ASL is used in the United States and Canada, while FSL is used in the Philippines.

American Sign Language is not spoken in the Philippines, so that would be pointless. You're better off looking for resources for Philippine Sign Language (FSL) and the first place to start would be a local university.

A person who does sign language is called a "sign language interpreter" if they are interpreting between spoken language and sign language, or a "sign language user" if they communicate primarily through sign language.
