Urgent help please - Can parents stay outside US for more than 6 months on GC?

[FamGC]

Please share if parents need to come back to US within 6 months or can stay outside US for more than 6 months as long as they are back in US within one year? They don't want to jeopardize their GC but would like to stay in India longer than 6 months. If there are any USCIS links clarifying this, that would be really helpful. Thank you very much.

There is no rule that if they stay outside more than a certain length of time, they will definitely be considered to have abandoned status. And there is no rule that if they stay outside less than a certain length of time, they will definitely be considered to not have abandoned status. It's all a matter of degree. The longer they stay abroad, the more likely they will be determined to have abandoned status, but all the other factors in their situation are considered in the determination too.
