OK, if someone likes the photo, I need ask an off topic question here. When I enter US at San Fransico, the inspector ask me how long I stay out side, then he wrote "not in 2 month" on my passport and warn me that I may lose my GC if I stay longer next time.
I thought I should be OK as long as I stay outside no longer then 6 month. Do I have to apply for Reentry Permission instead? Do I need to worry the note on my passport next time when I return? THX
