N400 Interview and lots of changes in application after filing

[jmd77]

I was divorced at time of filing, Now I am married and went for 2 weeks trip to India. I did bring 2nd wife divorce copy,her birth certificate, our marriage certificate, her passport copy, her previous marriage details. I have few questions for interview which is on 17th

 

1. whats best so as to not to get another 2nd date scheduling for interview. Should I print a new n-400 application and give them that new application as I filed as divorced, now i am married. What other papers I may need at time of interview

 

2. Should I file I-130 for wife  now or, once after I get my citizenship

 

3. Now another important question. I have read online that Once I become citizen and I file I-130 for her, it gets approved, then I can bring her to usa on k-3 visa. But my cousin said that the processing of even k-3 takes almost a year so its not worth it. I please need some expertise advice that in approximate how much time I can bring my wife to usa on k3 visa once after her I-130 is approved and once after I am already a citizen. Please help, I really need to be with my wife.

 

Thanks
