1. the GC is for 10-year period, will expire in 2016. Just simply fill I-90 Form to renew it in 2016?
2. after got GC, if relocate to other city, still need AR-11 to inform USCIS?
3. If I visit China, only bring Chinese passport and US GC, is that all?
4. If US born child will travel to China with parents, need to get Chinese visa in Chinese Embassy, and bring US passport, is that all?
Thanks for suggestion!
