My mother-in-law has been here for a year going through her change-of-status and just received her green card. I'm assuming the 60-day life-event period starts on the day she was approved. Also, we are in Florida and have to use the exchange for this state. I did some preliminary searching without registering her and using her yearly pension income of $9,500 and the site told me "It doesn't appear you are eligible for any PTC). The cheapest plan was 989 and the most expensive was 2000. We will be doing the official search here soon and I will post here what we found out.
