I have overstayed my F1 visa for about 4 years. I graduated from college in 2005, later received work permit approval and used in until 2006. Afterwards I went back to school for 1 semester, but I never finished it. Haven't left the country since my last entry -year 2000, but recently received a letter notification for being drawn from DV-Lotery 2011 (Green Card lottery). Now what are my legal options/if any for successfully changing/adjusting my status to Permanent residency, preferably without leaving the country in order to avoid the 10 year ban for reentry?
