Almost 15 months since application for green card sent for parents and it is still pending; it has taken such a long time ; however, they have received work authorization permit and ssn; but income negligible;

would it be a good idea to apply for their health insurance through marketplace (affordable care act) ,or wait until GC is approved. Has anyone (legal residents with minimal income, gc pending) received approval for marketplace insurance?

Any helpful thoughts would be appreciated. THis is very urgent as the deadline for market place insurance is looming (15 January last day) and this would be helpful for all the people from Nepal whose Green card is pending...

esp
- would it hurt green card approval process ?
- is it possible to get approved for health insurance through marketplace in this scenario?
- what other health insurance options are available or better compared to marketplace?

Thank you
