Good morning, my sister was married in my country before she came in US. When she came here she got married again but before that she tried to divorce from her previous husband. Unfortunately our cousin in our country provided her a fake divorce certificate. Because of that fake document, her case has been denied and her appeal refused.
But now she got a real divorce certificate from an American courthouse and canceled the current marriage and marry for the second time her American husband. They want to re-introduce again the I-130 and I-485 with a letter of withdrawal of the previous case.
Any advice for them?
