Just to keep you guys updated. today I went to the social security office to apply for unrestricted SS card. the lady as expected didn't know what i was talking about. first she told me, oh, with the EAD and this SS card, you will be just fine. I told her, this is costing me $120 a year. being prepared as other members from this group suggested, I showed her the memo. she looked at it, she disappeared for about 10minutes, came back asked me to file up an application and she will be contacting USCIS for verifications and that may take 1month. that was it. she took my old restricted SS card and told me to wait for the card.
anyway just wated to share the experience with y'all.
