Employment Based Greencard

I went for my interview yesterday. These are the things I did and I believe it would help someone. Tips: Dress professionally, arrange all your documents (I put all my original documents in one folder and copies in a separate folder. The officer was very nice. I was asked about what I do at my job, when I got in the country, asked me for my pay stubs. I had paystubs from June till September. In addition, wanted to see a copy of my original birth certificate which I showed to the officer. Asked for my tax return (gave a copy of it and my W2). It was a very friendly atmosphere we both talked about weather, life in general, food and how busy our jobs are in comparison. I was asked if I checked to see if there was a visa number available for me& I said yes. The officer stated am approving your case. The next day status updates to card in production. Good luck to everyone still waiting on theirs.
