在N400中，information about your marital history,，有一个问题date of birth of my current spouse's prior spouse,我先生不记得了，还有my current spouse's date of marriage with prior spouse,他也不记得了，应该怎么填呢，可以填don't remember 或者forgot了吗？
-I think it is fine.
如果这样填会不会有问题。谢谢。
-Just explain it if USCIS ask during the interview.
