Here is a short summary of my Green Card interview experience
at Newark.
On the day of the interview, we went in about 20 minutes before
the appointed time and handed our interview call letter to the
reception counter.
We were called in about an hour after the scheduled time. The
INS officer took our fingerprints and signature. He asked for
my employment letter (I had taken a more recent one along with that
submitted with the I485 application). He also took the
affidavit of support for my wife.
Here is the important part : along with our application
we had submitted our birth certs. (which you may realize
read unnamed, since that was the way things were done in India,
the registration took place prior to the naming ceremony).
I had however submitted an affidavit by an elderly person
swearing that the child referred to in the BC was subsequently
renamed as ....(yours truly). During our appointment
however, the INS officer asked for an affidavit from a second
person. Luckily, we had taken affidavits from two others and
that was more than adequate. That was it - our passports were
stamped and we were told our cards should arrive in
6 weeks - 2 months. Since we were moving apartments, we gave the
officer our new address.
