I get incredibly frustrated reading posts from people that think "maybe" they want a green card for the future, or for travel, or just to have. So many people want the green card to move permanently to the US, start their lives their and follow the rules; the rules so clearly all over the internet and especially this forum if one only looks. How many legitimate entrants with US goals lose their 'place' to those who enter but never really want to go to the US to live and get out as soon as they can to go to their home country and only enter the US to keep their status. Makes me so cross.
If you don't want to permanently move to the US to become a Permanent Resident, exactly the purpose of the Green Card, for goodness sake don't enter the DV lottery and take a visa from someone else.
