Hello, I won the 2023 DV lottery from Europe, and my rank is around 15,000, I am in the US legally now for a few years. I will file for adjustment of status. I see that historically I can file I-485 around April of each year, but the rule says my I-485 has to be processed by September 30. I am afraid I will not make it on time. Should I write a cover letter to USCIS with an expedite request? Should I put "Attention Expedite" on the envelope? Can I file I-485 in advance on the month that posts next month's numbers that will be above my rank, and include a copy of the USCIS memo allowing for somewhat early filing? Also, is it enough to simply translate my high school diploma into English, or do I need a professional evaluation of diploma service? Thank you in advance for the answers.
