the reason i got confused because today i went to the DMV in South Carolina, they sait they will except Stamp that said, will accept, "I-551 processed and I-551 approved".
I haven't seen approved. Secondly, they said that they'll issue the license for 1 year only. I thought that sucked. So i left because i did not want to get paper license in interim for 1 month and loose a photo identification.
Third they said that we no longer need to change, "valid for work with INS-authorization" on social security card for driver's license purpose.
I do understand that we need to get the new SS cards, but i think i will wait for actual plastic cards(green cards) to avoid any confusion as DMV gives license for 5 years if you have actual plastic card.
