We just came back from the interview and don't know whether I should be happy or should I be sad.
We reached at 9:35am for 10am interview and were called around 10:20pm by a Chinese fellow. He said that he is running late so will be quick. We were glad to hear that.
He asked our Drivers license and we then took oath. Then he started going through I-485 paper and I-130 paper with questions on address, which schools she went to, confirmed phone number etc ... Then he saw my wife's Birth certificate and said how come your wife has same last name. We said that most of families have same last name there. He asked if you guys are related. We said no. He was still not convinced and kept asking it again and again throughout our 15 min interview.
He then asked to see original marriage certificate and our son's date of birth certificate. He asked if our son was born to both of us and we said yes. Then asked give me documents proving the relationship. I gave him a bunch of documents and he asked if he can keep it. I said yes.
Then he said, I have to do some clerical work and then make a decision on your case. We asked if anything is wrong? He said not so far. Your case is straight forward and unless I find some issue in your application, you should get a welcome letter if we approve your case. I asked if there is a need for 2nd interview and he said not likely. I asked how long will you take to make a decision, he said maybe today maybe in next couple of days. He is not sure. I asked him that we are traveling in first week of Feb and he said that's a long time, you will hear a decision by then. You can bring welcome letter and get your passport stamped if you do not receive your GC by then. But don't travel on AP after GC is approved. But still all depends on the decision he makes.
In 15 min everything was over and we were out confused that I haven't seen any such thing so far in any forum. I had initially planned to celebrate but we both are so glum now
....
Since our application status does not show online, it is very hard to track the progress. I am thinking of calling USCIS tomorrow to find out if the decision has been made or not. Else I will have to call next week.
