I had an interview at Singapore embassy. Interview was fine but only pending the professional translation of my birth certificate to English is needed. They returned my passport and photo. Requested me to submit the translation online and then courier back my passport, photo and translation birth certificate to them.  I forgot if the original birth certificate needed to send back together with the translation or only the translation document only? Anyone had the same experience like mine? Your advice is needed ..

What is AP?

I am in Singapore. I got issued the Form 221 (g) because I need to get my birth certificate translated to English. I was wondering if there are any recognized translation services accepted by the USCIS? does Notarization required? Any help would be much appreciated. Thanks in advance.
