Hi Britsimon, thanks for your help! Regarding your AOS, do you now have your GC or still waiting? Also, does the AOS come with a work permit, allowing you to stay until the decision is made? If you could direct me to the appropriate thread for this and my many other questions that would be brilliant! And what was you approximate CN if you don't mind me asking? thanks again!OK - if you have not already submitted the 260 you should hold off for now. That is the point at which you are thought to have declared immigrant intent. Simply entering the lottery is not thought to be that point.
If you have completed the 260 form already then yes you will have to be honest about that when you renew your E3 visa. It does not automatically disqualify you for the E3, but it might making that a little harder. Others have achieved temporary visas by showing that they have ties back home and that they fully intend to work within the rules (i.e. yes is interested in moving to the USA but will leave as planned at the end of the E3 unless other avenues open up).
Regarding aos or CP - I was around the same level this year and opted for aos. So far I don't think that was a wrong decision - the early submission (30-45 days) helps but you have some options to nag them into interviewing you also.
