My mom was sick in hospital (Final Stage Cancer Diagnosed)when she was visiting US. Her visa thus expired.

I have had my green card since 2013, but I can not take citizen exam until year 2018. We are in New York.

Someone told me with me filing I-130 my mom could purchase health insurance with the I-797 receipt.

But what will happen if I file I-130 without I-485 followed, or shall I file I-485 and wait for denial, will my mom be deported immediately? She may die on plane.

Thanks.
