I am a DV lottery winner and I have filed anI have filed my I485 more than 10 months ago for DV lottery but have not been able to get an interview yet. As DV lottery cases for 2016 are valid till September 30th 11:59 pm and will expire after that if not approved, I need to finish it up till then and otherwise I would lose the opportunity. As a backup, I am planning to file an I-140 for NIW but need to make sure that filing an I-140 at this time would not interfere with my current pending I-485. Can the situation be different because my I-485 is based on DV lottery not other types that are eligible to file I-485? Any idea is appreciated.
