I think you have to pay into the system if you are a permanent resident alien. If you are here legally, not a citizen and never worked, I would guess not. Look at it this way, disability benefits are for people who can't work due to disabilities. Welfare is for people who don't want to work. SSI benefits are available to all qualifying United States (U.S.) citizens; additionally, residents who are not citizens are sometimes eligible for benefits, including U.S. nationals, aliens, and other non-citizens. As a general rule, an otherwise qualified immigrant who is facing deportation or removal is not eligible for disability. For more information you can refer vthis link.
