US Immigration from Canada

I'm American, married a Canadian girl in 2010 and we were living in USA until 2014 when we moved to Canada to help her ailing parents. My wife had a green card which she gave up upon entry to Canada. As a previous green card holder, would she have a shorter re-approval process, and if possible, how to pursue that track? PS we are still living in Canada, in the Toronto area.

Can you please tell me if they accept I864 form with edition dates that have expired. I have looked online for up to date forms but can t find any. The most recent one I can find is dated 03/10/21 and the expiry date is 9/3021.

Thanks for any advice on this.

My friend who recently became a US citizen told me that by taking oath, you renounce all other citizenship. I already submitted my n400 and I pray to the heavens I don't lose being Canadian.

Does becoming a US citizen actually cost me my Canadian citizenship? Please advise.

Thank you.

When we filed the I-129F few years ago, NO2 has an A number for me as the beneficiary. Now we are filling the I-130, it that still my A number? or it is invalid because I did not get the visa? I read some posts here that says if it is in fianc NO2 it means nothing. Not sure what is correct
