Thank you, though you are not 100% correct in your perspective. I have spoken to immigration and know that an extension is possible, but as with most red tape things need to be done a specific way. That's what I'm trying to get sorted. I had insurance, but as I said I was employed and there were issues with the company. I have never tried to avoid doing anything or tried to get away with anything, it's just something unfortunate that happened. And yes, I was too sick to get up at all for a long time, and still not well. What you said about oxygen on planes isn't correct. You can't take oxygen bottles. Only specific models of portable battery operated concentrators are allowed, and with enough battery power X 1.5 duration off your total trip. These are not typically distributed here, and are also extremely expensive. I've done my research about this. And no airline will want to take responsibility of a passenger who literally can't breathe. Trust me it's obvious when you are collapsing and gasping for air. So there are cases for almost everything, nothing is black and white. I'm just asking for advice and particularly regarding visa services or 3rd party agents who might help in cases like this.
