actually I take it back. one must be lawfully present to be eligible to ACA.
lawful presence includes: green card; asylum applicants; illegals granted
holding on deportation and nonimmigrant visa holders.
I don't think Visa holders are eligible for the tax credit though. so you
may be better off buying traveler's insurance to deal with emergent care and
send your parents home for continuing treatment. http://goo.gl/SXRaIe
