Working for the same company for 9+ years (7 yrs in the USA and since last 2 years in India Development Center for the same company). I received my GC in June 2016 and have got the physical cards delivered to me in India. Lost my father in Nov 2016. More than 9 months passed since GC - never traveled on GC so far or worked for the Sponsoring employer even for 1 day in the USA. I want to work and live in the US but for immediate time (next 1 to 2 years) I need to spend more time in India to console and support my grieving mother. My current company does not have any immediate work for me in the US. I am looking for options outside my company to come back to the USA. I am also considering an opportunity local in India.

I believe your circumstances are so unique I think what you could do is at least come to the United States as early as you can and take up that job even if it is for a few pay periods with the intention to stay in the United States as much as possible. You can also bring your mother on a tourist visa and keep extending that as well. At the very least you should come to the United States present yourself for work, whether you do it through an email or whatever method and if the company says they don't have a job right now at least you have some hook to the argument that you had presented yourself and they didn't have a job for you. I think you will be able to keep your green card safe eventually is my guess.
