Filing I140 while outside India

Hi

My labor just got approved and I want to file my I140. I am currently ouside the US. At the I140 stage we need to state our preferance for AOS or CP. Can I elect for AOS while filing for my I140 assuming that I will be back in the US when I actually file my I485 or do I need to present in the US even when filing my I140 if I specify the AOS option ?
Are thare any INS sites that give clear instructions as to this matter ?
