Hello. I have my citizenship interview in a couple of weeks. I'm married, but applying on basis of GC + 5 years. I have had my GC for more than 10 years (renewed my GC after 10 years also). My interview letter just asked for green card, passports and photographs. I keep seeing many threads here where people are talking about taking tax returns, wedding certificate, etc. If I'm not explicitly asked for these things, do I still need to take it? Please advise, thank you.
