I used to hold H4 visa. My hu*****and and I applied for green card, and now our 485 is pending. I applied for EAD (for SSA purpose) and Advanced Parol and went back to China in the past summer. Now I don't plan to work and don't plan to travel out of the U.S. in the following year. Do I have to renew my EAD (my EAD will be expired in three months)? Thank you for your advices!
