Haha...yes..and to make it even easier..it has to be the same format as her offical birth certificate/translation which you must have submitted with the I-129F. Get the divorce ceritifcate from the same place. Actually, we didn't have to submit birth certificate for I-129F application (at least not to USCIS), only fill out forms, copy of her passport, and some other stuff, although I understand she may need birth certificate later at time of interview.
