I used the I-551 stamp to get my unrestricted social number card. later, when i made a infopass appintment, the officer cancelled my stamp and told me my case is pending with nothing else(i think they just want to wait untill full two year marriage, then make a decision). Why social security administration already verified my stamp's validity and then the officer can cancell the stamp. Can i use the unrestricted social number card to work without employment and Do i have any responsibility for not reporting to social security administration about my I-551 stamp cancelled
