Hi all, I just wanted to know something you get your green card from OGP once you start your 18 month contract, do we have green cards forever or do at some point do we become citizens. Reason why im asking is because i also have my eye on airforce nursing, and they are so strict , they 'only want you to be a citizen' not an 'alien' resident that they call us..Please tell me that we get full citenzhip after a while or will i have to be an alien for the rest of my life..
