Yes, she has health issues that contribute to her weight. She's a bit fluffy but she's certainly not obese!
She said they were shocked as they went in thinking they'd be wanted. Own their own home, financially stable, stable relationship, can afford to provide a high quality of life with private education, travel, etc. She's making 2017 about "her" and hoping that she'll have lost enough weight by the end of the year to be reconsidered.
But anyways, I was absolutely wrong about the issue being immigration status - so at least that's something that's not an issue!
