Adjustment of Status - I-485

I had my interview yesterday (6/18/2018) at Chicago field office after 1 year of application (employment based - EB1). It took 15min and wasn't difficult. He verified the basic information I provided them before. Due to the expiration of my medical exam file (valid ONLY for 1 year..unfortunately mine expired 2 weeks ago), officer asked me to renew it. He didn't find any other problem he said. He wanted to learn if I still continue to work at the same place and if I can prove it. Before going to the interview, I prepared I-485 Supplement J file signed by my employer. He took it and added into my other files. It is also good to print out latest I-94 showing your travel records. He said as soon as he gets my renewed medical exam results, he will approve my case and green card will be send in 2 weeks. Good luck to everyone.
