I am an immigration attorney and have many non-citizen clients

I am an immigration attorney and have many non-citizen clients that need help applying for Medicaid and SNAP benefits. Is there a place where I can view exactly what documents are required for different classes of non-citizens to obtain benefits for Medicaid? Specifically, refugees, asylees, humanitarian parolees, Special Immigrant Juvenile Status children. Also, is there a way to obtain temporary benefits for non-citizen children who are waiting for approval of their Special Immigrant Juvenile Status?
