Copper Congrats. The day she receives her naturalisation certificate (after oath) she will have to fill out form I-130 and you send in the following forms:-copy of naturalisation certificate, I-485, I-765(work authorisation), Advance parole(if you are planning to travel; 864-Affidavit of support by your wife) and in some instances medical exam- depending on district office. They have moved the center to a chicago box office in some states for sending these applications.Some states (like oregon) can send in these to the local DO until 1st of April after which they need to be sent to Chicago. sO SEND THESE IN AS SOON AS SHE IS NATURALISED- DONT HAVE TO WAIT.
