Hello guys,
My mom is a greencard holder and she traveled to Nepal. She was supposed to come back to the US waay before 6 months, but as you know she is stuck and it is likely that she may stay there beyond six months.
I know USCIS requires some pre-documentation if a greencard holder is going to be out of the country for more than six months. Now, given the circumstances, do they still require documentation or since it's obvious and nothing is needed to be done?

I wanted to ask if someone in the similar situation has reached out to USCIS or looked into it.

Thanks in advance
