My wife's permanent resident card is expired soon. We have not applied
for citizenship. I tried to find the answer on USCIS website but it's
not clear. it says I-175 is to remove conditions. My wife is not a
conditional permanent resident as far as I know (that is for couples
married in the US I believe).
What form do we use for this? Is applying for citizenship enough? I
mean, does that somehow "extend" the green card?
