Advance Parole

I traveled to Haiti with my 3 US Citizen Kids on AP for christmas. I was nervous about the experience coming back. We flew into Logan Airport in Boston. I went to the visitor's line at the immigration check point. I handed our passports to the officer. She was very friendly. She checked the kids in first. Then took my fingerprints and picture. Then she said I need to send you downstairs for your parole to be stamped. She called for another officer and told us to wait behind the blue line. She didn't ask any questions.
After a few minutes the officer came to escort us down to the waiting room. After about 20mins. the officer behind the desk calked my name and said you're all set and told us how to exit. Again no questions. Everything went super easy with no issues.
The only thing I would advise is to be clear in your mind about any potential inadmissibility issues. I was cocerned about the 10 year bar and another issue that I had to have an I601 waiver for. I knew the 10 year bar was a non issue due to the new ruling by BOA. But I had no proof that the waiver was approved so I filed a FOI request and got a copy of the aporoved waiver. That cleared all inadmisdibility issues in my mind. I was,at peace that I did my homework and would at least jave an answer if they raised those issues. But fortunately none of that came up. Moral of the story is do your homework then travel on your AP. Everything should be fine.
