I have been in the US on an F-1 visa, and it has been several months since I last was outside the US. I am on DV2017OC0...14xx so I expect it may not become current until July-September 2017. I am considering a vacation, leaving the US for a few weeks in December 2016 and returning in January 2017. I would probably choose AOS over CP, although I am still considering that and trying to gather information about what would offer me a fast enough processing time in my case.
I have a few questions - would be very grateful for some comments from anyone who can answer them!
1) If I submitted my DS-260 now, would that demonstrate immigrant intent to a nature that would make it problematic to leave and re-enter the US in Dec2016/Jan2017, or cause problems during the AOS process?
2) If I waited to submit my DS-260 until immediately after my trip home in January, would I be breaking the 30/60 rule?
3) If I waited to submit my DS-260 until 2 months following return to the US in January 2017 -- yet keeping in mind I have already received a lottery win and that is presumably on record -- would entry to the US be a problem given that I have won the lottery, and that I did enter and then subsequently complete DS-260 and apply for status?
4) In the same scenario as (3) where I wait to submit my DS-260 until 2 months following return to the US in January 2017, I wouldn't be submitting my DS-260 until some time in the middle of March. Would that risk prolonging my already-tight deadline to get an interview with my high case number, increasing the chance that I wouldn't get my interview before September 2017?
