So, back when my wife first landed here, everyone online told us to get her an SSN ASAP. We got one approved at our local office, and then sent off our I-485 before her SSN arrived in the mail. However on the I-485, we checked the box requesting an SSN. We read somewhere here that we needed to do that so that they would update her last name now that she is married, and to remove the "Valid for work only with DHS authorization" part of her card. But now my wife is worried that she will have two different SSNs which will cause all sorts of problems. I personally think that since the I-485 has the same passport number and I-94 number that we provided when we applied for the SSN at the local office, shouldn't they see that there is an existing number with that information and not cause issues? I know someone who had a SSN mix up when he was younger and it still causes him problems to this day, and I don't want the same for my wife.
