Hello! My interview will be on May 23rd. Is it ok for my USC husband to make another I-864 and send it to me since he was not able to keep a copy of the original which he sent to NVC? I read in the US embassy website that once you sign the I-864 it is definite meaning it's good until the alien becomes a citizen or until after 10 years unlike before that you need to renew after a year. If he makes another one then he signs on a different date...will that cause problems?
This also goes the same with my DS230...I need to make another one and it will be on a different date than as of the original.

Please advise thanks.
