Yeah, we all should have remained in India. Definitely.
Thank you very much for pointing that out.
I'm only pointing out that if you didn't want your mom to remain alone one sibling could have remained in India. It was very clear that your mother would not be able to move to Canada for 4 years at a minimum and technically there was never a guarantee. When choosing to move there are sacrifices. There are many other immigrants in Canada facing the same issues with much older parent(s). Your mother needs to focus on reestablishing her ties to India so when you are employed and get your NOA she an apply for a supervisa.
