I have a question regarding proper time to apply for N400- US Citizenship for my wife. She became a US permanent resident in 2007. I am a US citizen and we have been married in the US for the past 4 years. I understand that for permanent residents married to US citizens, they can apply for citizenship after 3 years. Is it 3 years from time of receiving permanent residence or 3 years from marriage? If it is 3 years from receiving permanent residence, then I would have to wait another 2 years before applying for citizenship. If it is 3 years from marriage, then nothing should prevent me from applying now, correct?
Thanks in advance.
