I’m assuming this is for abroad in general but please check with your consulate. We all know the US government can be funny about things. I received this information of the US consulate in Rio de Janeiro. They were very helpful by email, answering my first one in 2 days and my replies on the same day! I couldn’t believe it either.
Child and both parents must be at the Consulate for the appointment. Please see below the required documents:
- Parents’ valid ID document (passport, RG or driver’s license).
- DS-11 Form (please fill out but do not sign it)
- Child’s original U.S. birth certificate (or CRBA – Consular Report of Birth Abroad)
- Child’s previous U.S. passport
- U$105 (or the equivalent in reais)
- 1 recent photo (5cm x 5cm) – in color with a white background
I personally also recommend photo copies of everything. I don’t know if it just a US consulate in Brazil thing but people want copies here.
For more information check out this government site. It provides answers for single/adoptive/guardians as well as other useful information.
It should be noted that if you attempt to be humorous in your emails to the US consulate they will either ignore it or be annoyed by it.
