I-130 Translation question

[metaxas 0]

Hi, I am getting a friend to translate my wife's previous marriage divorce decree into English from Hindi. I know the friend needs to attach a translation competence certification to the translation. Question is, the decree is several pages long, does there need to be a certification on each page, or just one certification for the entire document? 

And if its a single certification per document would it be better to put the certification at the end of the translation, or attach a separate certification page at the beginning of the translation document?

Certifying the translation competence is a simple statement on the same page as the translation.  Read those instructions again carefully.  Interpret them "literally" and act accordingly.
