During my wife's L2 interview.?
If you were banned for life how did the consulate advise you to apply with a new petition? You can apply but the bar remains and youll have to overcome it. Misrepresentation is one of the top 3 thou shalt not do ever sins of US immigration. It virtually guarantees youll never get a US visa again. If your visas were cancelled with prejudice and you were told you have a lifetime ban, I wouldnt bother applying for any US visa. Youd just be wasting time and making donations to the US government.
