The situation:
My parents has green card, return to China end of December, 2008. Want to come back to visit us early December, 2009. So they stay in China for 11 month before they return to USA. The are 66 and 72 years old.
The questions:
1. Is it possible that they will be blocked at the custom, not allow to enter into US (asked to return to China immediately) since they left USA for 11 month? (The law says if they return within 1 year, no return permit is needed, but also says they better return within 6 month).
2. Is it possible that they will be allowed to enter into the US, but their green card get canclled by the US goverment?
3. Or there is no problem for them to come back to US since it is within 12 month limit.
4. What can we do, and how to do it, to provide evidence that they did not abandon their green card? Since they live with us, and depend on us, they do not really has bank account, etc in US. They applied social security card, that is all.
Thanks in advance
