Concern about the interview

[ao_cons 1]

Have you thought that if they'd kept the records, that the husband/greencard holder would be in trouble now for lying? Like got his visa/LPR status revoked? Also why is the case at NVC now? What exactly was the husband told? Is it starting over, or was the case returned to NVC? Is it same case number or a new one? I believe an NVC case has an expiry date once it is approved. Why did he get a letter about this many years later?

In the DS-230, the applicant will be asked if they've ever been refused as US visa before and why. That is if my memory serves me right.

My advice is to try to get a competent insider to tell you or your friend just how much iinformation is kept in the case of visa denials. You could try Yahoo Answers, other areas at VJ, or even a reputable immigration lawyer. Normally I don't recommend lawyers, but in special cases a good attorney might be helpful.

BTW, if the husband applied as single and he was really divorced, technically he didn't lie.

It would seem better to tell them the two had a serious quarrel if they ask about the divorce. If the wife were to tell the truth, she would get denied for sure anyway. 10 years later, she may get the visa by just saying it was a quarrel or something. But this is not legal advice.
