Since there was no positive response even calling the phone for information, I decided to make an appointment through the InfoPass. I traveled from Brazil to the USA with my son for this appointment.
I think that was my luck, the consultation took place on May 1. I was very well attended, explained my situation, that my son will turn 18 years old on May 20th, and asked the officer if there was a possibility of advancing the process.
The officer who attended me, found the process, that was still in Phoenix, and said that they would manage the process to come to NY (the selected office for the interview), and it would take about 7 days, but it would still have to be appreciated and that he could not tell me how long time they will take to do it and not even that we would had a chance of the petition be aproved.
As I had managed to stay for 10 days I decided to wait. In May,7th I received an email asking me to contact the USCIS NY via phone .I phoned to the indicated number and the officer asked me what time we could go there the next day(05/08).
So I went there in the mornig with my son , the officer that attended us asked a few questions confirming the information provided on the form, and after that asked us to wait outside . The time she returned with the oath to be signed and then handed the American flag for my son ,we were very happy and surprised!!
After that she asked him to repeat the oath with her and finally gave him the US citizenship certificate.
With your assistance I could realize the dream of my son!
I´m writing to thank your attention to my case!!! Thank you very much!!
