It depends where you are interest in like in your area of New York City, if that is where you live in. If not in a big city, you can try to go to Seattle, Washington where there is a Deaf communities and Seattle Central Community College with the Deaf program. I went there for college for two years.
Also you can try going to Albuquerque, New Mexico where there is a lot of Deaf people and there is interpreting programs at the University of New Mexico and maybe you can teach ASL to hearing and some deaf/HOH people how to sign at the university. My family lives there both in Albuquerque, New Mexico and Santa Fe, New Mexico(Santa Fe have a Deaf school). I had lived there before I moved to Canada.
I don't know but the only solution is to go to your college counselor or at the VR(vocational rehabilitation) you can ask the counselor about where you can go and teach ASL and be among Deaf/HOH people in their Deaf community. Just have to find the right place to look for and hope to settle one. Mind you, you need to travel first before you move so that you can study and learn if that is the right place for you to stay in.
Good luck!!!
