I am a US citizen who has lived outside the US for many years and I am trying to obtain a green card for my wife, via form I-130 and the IR-1 visa. We have documents such as apartment contracts, bank and utility statements, etc. showing a "bona fide" relationship but almost none are in English.
I know that the USCIS do not require notarized translations or originals, but do they require the translation of the entire document? For example, an apartment lease is very long, and even the first page has hundreds of technical words that are irrelevant to the main claim that we leased an apartment together. Would a marked-up copy showing our names in English be enough, even if it left the rest in the native language? Similarly for utilities, do I really need to translate the cost per kWH and tips for saving electricity that are written on my electrical bill?
