In NY city INS office , they did not take Advance Parole,But..
I had gone to NY City INS office on Friday May 17.
They took the original of Aproval letter of Permanent Residence, finger print and photos and did not stamp the passport.
I heard that in California , they had stamped the passport on May 17.
From your posting , they are taking Advance Parole Visa. THat was not done in NY City INS office.
Looks like it is not standardized in different INS offices.
As it is a new Rule the offices really do not what to do and our GC process is currently in a mess!
