Officer was very polite and welcoming.
Started by checking that all documents were previously sent. Asked if we have anything else to add hoping we have some extra pictures.
Then she went verbally through few of those questions included on the application form, like those related to ever been involved with terrorism, communism, etc.
We were given the chance to modify how the name would look on the green card, etc.
Overall, very nice, polite and stress free.
