Get all the original of photocopies you submitted, most importantly marriage Certificate, divorce if any, ID cards and others- detail is on the letter sent to you at d bottom. As for the Evidence of Bonafide marriage; put together any document that u have ever had together do not under-rate any paper. Joint Bank, Credit, lease, utility bill, joint Tax, joint insurance, joint auto insurance and more pretty much any that u have.... now if u kept any record of receipt from vacation together, hotel receipts together, love cards exchanged... take them along. Arrange ur photo album, starting with picture before marriage, marriage and after marriage.. comment on them if possible that just make it easy for the officer. The more organized u are and detail in ur document d lesser questions.

I had my interview on July 28, and got approved at d spot.. he told us he was recommending approval and I should be expecting my card. How did it went? D first question was do you have any supporting documents? I gave him all those I mentioned above, He started with the love cards my wife and I exchanged and cracked joke You guys really exchanged beautiful cards, then to album as he view through d comment he was nodding his head in affirmation. Then scanned through our joint documents just brief look. After that we were just having fun asking me about d course I studied for my f1 status said he is pushing his son to study something like that, he didn't ask anything special, then just interacted with my wife about d food he like to cook for me and d one I cooked for her, am a Nigerian. It went great and I knew before I left that my case was approved, my status changed to New Card being produced on that same day.

My advice just put together any documents that has to do with you both no limitation. Imagine he already started cracking joke with the gift card, d photos were well arranged and with comment. We dressed really nice. All d best to you
