Well I had my interview for naturalization.
I arrived at the Miami office early with most documents I could think of in tow. I waited about an hour or so and I was called in. The officer was very polite and respectful and began the procedure with the civics test and then proceeded with the oral and written English test. Then the Officer went into my biographical data, work history, international travel history (of which I had dusins) in some detail. I am glad I memorized the addresses for the places I had worked during the past 5 years, but I had to check my list when I was asked for zip-codes. It was also useful that I recalled the dates of my last few international trips. After that the officer went through the long list of "yes" and "no" questions and finally,,, asked to review my past few years tax returns. This item was not mentioned in the invitation letter that I received, but I had brought them anyway. It too a little while and the officer said that they would keep them for reference. They prefer the electronic copies that you can download from the IRS website so I recommend to do that.
In the end the officer informed me that my petition for naturalization was approved and printed out a one page document for that purpose. All in all the interview lasted one hour. I was asked to wait out front for 1-2 hours and after some time a supervisor called my name and informed me that my oath ceremony would be 3 days later.
All in all the process was much faster than i had expected for such a busy district as Miami. In total 5 months. As I applied a few months before my 5 years the entire process of immigration to citizenship lasted 5 years and two months.
I will need to get a passport quickly as I realized that it is not legal to travel in and out of the US with your country of origin passport even it is still valid.
I guess this is it then... I appreciate the people on the forum that I have followed since my DV 2014 and good luck to everyone.
