| My father immigrated to the United States in the 1960s and somehow lost his landing papers along the way. I do have his US naturalization certificate, showing that he was already a US citizen at the time of my birth (disqualifying me from Chinese citizenship?). However, the naturalization certificate says "it is punishable by us law to copy, print, or photograph this certificate" so I'll have to break the law to send in a copy to HK immigration. |
