I couldn't find an answer online so I wanted to post it here. Hope, someone can answer my question. I got my green card in April 2016 through my employer. I also got a green card for my wife while I applying for a green card myself and she received hers one month after me in May 2016. In a month, I am eligible to apply for citizenship. Can me and my wife apply to citizenship together? Or do we have to apply separately? She can start applying in Feb 2021, I can start applying in January 2021. If we can apply together, what are the documents we need to submit? Thanks in advance for all your help!
