Interview took place in Mt Laurel NJ

Waited for two hours and was called by a middle age gentleman. We took our two-year-old with us. No questions were directed to my husband. The IO asked some weird questions like: why didn’t I marry my first son’s father? Why did we waited two years to get married base on the age of our son together? My husband is much older by double digits, so he asked if our marriage is real? He didn’t ask how we meet.

The IO took:
Original I-94
Joint phone bill (copy)
Joint medical Insurance(copy)
B/Certificate (son)

He told us to expect the Green Card in two weeks.
01/20/2017 - Received GC in the mail

I am overjoyed. Feel free to ask any questions.
Good Luck All !!!
