Sharing my experience regarding AP expiry date while returning to USA at POE at Bombay:
India Immigration officers are NOT saddist to extract money out of you...But, I did face slight problem on AP date...My/my families AP Expiry date was 12/8/2005 and we were coming back to USA on Aug 15, 2005.
Immigration officer told me that my/my families AP is expired on Aug 12 & I cant travel.
Then, I have to tell him that my AP is expiring on Dec 8, 2005 (AP expiry date 12/8/2005) and NOT on Aug 12, 2005 because USA dates are in the MM/DD/YYYY format. He did not listen & called his Boss/Supervisor. His Boss also told me that our AP was expired on Aug 12, 2005. Then I tried to convince his Boss that USA dates are MM/DD/YYYY and my AP is expiring on Dec 8, 2005 and NOT on Aug 12, 2005...But, Immigration officer & his Boss kept on arguing with me that my AP is expired & we cant Travel.
But, all of a sudden near by immigration officer intervened & came to our rescue & he told his Colleague and his Boss that what I was telling was right and my AP is valid upto Dec 8, 2005. Then he allowed us & stamped our passports. We all family members were in "tight position" for 5-10 minutes but my arguments were valid & was nothing but truth!
So, take care of this AP "Date" issue/problem and you wont be in trouble at all!!!
Good Luck...
