I am posting this for my husband and his twin brother who came legally to the US in 1958 from Germany with their Mom and number of siblings. Their Mom was naturalized and became a citizen in 1971 I believe and, at that same time, the 3 underage children were given citizen status with her. Now, at 62 yrs., they have become of age to get Soc. Sec. They both have worked all their lives, paid to SS and are being told that they are not citizens and have to acquire their citizenship papers from uscis. This is proving to easier said than done. My brother in law, husbands twin, has had his n600 accepted by uscis but never received a receipt or any indication from uscis that his papers are being processed. It has been 6 mos. since he filed them in Minnesota in St. Paul. My husband has filled his n600 out and tried to file it but uscis will not accept due to too little info. He gave them what they wanted and they won`t accept it. His mothers papers have been lost by the older members of his family and so there is little to give uscis. We don`t know what to do now. uscis said they are running a background check on my husbands mother and will call him when they find out something. I don`t really believe uscis calls anyone back. Does anyone on this forum have an idea of what we can do now. My husband served from `66 to `69 in the US Army and his papers clearly say he is a US citizen but SS won`t accept that. HELP!
