My Wife just got a request for initial evidence to include a long form birth certificate.
"Submit a copy of the birth certificate of other primary birth record issue by the appropriate civil authority for the applicant. USCIS will only accept a long form birth certificate which lists at least one parent. If the birth certificate or other primary birth record is not available, you must submit acceptable secondary evidence and a letter from the government or other authority"
In the initial AOS package we included a copy of her original birth certificate and it is bilingual (SEE attached below). I am not sure why they did not accept it and where we would get a "long form" birth certificate done.
