How do you apply for green card after returning it to the immigration?

If I have understood clearly, then you mean to say that you have returned your green card back to the Immigration. Can you be more clear about why you had to give back your card? If your green card was revoked by the USCIS, then your are chances of applying to get a new one is very thin. You have to give in your green card when you have taken the Oath of allegiance during the naturalization process. In that case, you will not require the Green card as you would have become a US citizen by that time.
