公民為 九十歲母親(父親已去世)做親屬移民。 母親在和我父親結婚之前很久， 大概1960年離過一次婚， 但是所有的文件都找不到了， 可不可以填I-130時不申報這個前配偶, 謝謝！
-You may just put the information in I-485 and explain in Part 14 Additional Information of I-485 that "I missed my marriage certificate and divorce certificate from my first marriage because it took place more than 60 years ago". Then, also explain it during the interview if the immigration oficer asks this question. No big deal, anyway.
