Hello mom,
We had our interview today. It was so quick (15 minutes), and the officer was really nice. The interview was super easy. The officer called our names, and we followed him to his office. We gave the oath, and the officer asked questions from I-485 (last arrival, graduation date, visa status, and security questions). Also, the officer asked about the question that we made the error. Then he corrected it and told us it is not a big deal. Same time, we informed about the error and double filing (we got our rejected package yesterday). The officer did not ask for any documents, and he asked us to sign the I-485 for the correction the officer made. Then he asked about our studies and told us that the case was approved. We gave the job offer letter, enrollment verification, and tax transcript. When we come to the car park, the case status changed to "New card is being produced."
Our special thanks go to Mom for her invaluable suggestions and guide us in the correct direction throughout this process. Really appreciate your time and support.
Also, we would like to thank everyone in the forum for sharing their experience, and this forum is a great resource. We wish everyone in this forum good luck.
